How to Start a Clothing Brand with Less than $1,000?

9:12 AM Add Comment
Starting a clothing brand has always been a smart business idea. As long as you have fresh and innovative designs in mind, which you feel would set you apart from contemporaries out there, you should be confident in having your clothing brand. What makes this business idea difficult is having a tight budget which limits your capabilities as a business prospect. From design conception, materials to mass production; development costs will accumulate and these factors will eventually take their toll for your clothing line.

When you start a clothing brand with a limited budget, you have to be conscious of the different cost factors involved in garment manufacturing. You cannot be complacent in spending your money or else you’d end up spending your money on unimportant aspects. In this article, we will discuss how to start a clothing brand with less than $1,000 by focusing on the things that truly matter so that you stay within your budget.

1. Design Concept:
The design or concept serves as the backbone of your clothing line. This is the first step your budget should be allotted to. If you happen to have graphic design skills or know how to draw by hand, then you can do the sketch/illustration yourself and save up on graphic design expenses. Hiring professional graphic designers can be costly. Taking advantage of freelance graphic designers (like on Fiverr) is the way to go as you can save up on professional fees while usually getting sufficient quality. You just have to get your idea across; a design sketch doesn’t have to be a masterpiece.

Come up with a design that is relevant to the brand you’re trying to establish. Keep in mind your initial design will be basis for your future designs. You don’t want to release designs which are far off from each other as it can confuse consumers and will be detrimental to your branding purpose. Create a design which caters to your target market so you can build a niche in which your clothing line belongs. Overall, the cost here is minimal or even zero.

2. Tech Pack:
In the world of apparel manufacturing technology, a tech pack is a professional design production file in which your clothing will be fully specified. The tech pack includes info such as materials, colors and other specifications needed for your clothing product. Furthermore, it’s also the basis for preparing a cut sheet which is a yet another production file containing the sizes and respective dimensions for each part of your clothes. The tech pack and cut sheet will serve as the guide for the manufacturers once your product is ready for sampling or mass production.
Apparel techpack
Fig: Apparel techpack
When it comes to tech packs, you probably need some professional help. Some experience is needed to assess which materials make sense, how the sizing of your clothes should be and what stitching to use. Otherwise you might end up with a tech pack that contains a design that is impossible to stitch together or doesn’t turn out as you want to. Also, a certain format has to be followed so that the factory understands what to do. The cost for getting an individual tech pack made vary widely. You can already get a professional tech pack from USD50 (see reference at the end of this article) or commonly spend something between USD200 and USD400.

3. Sample Your Product:
With your tech pack and cut sheet completed, you are now ready to sample your clothing product. The sampling process is a crucial part of the manufacturing process since this will be the trial phase for your initial clothing concept. Expect to discover some errors or rooms for improvement along the way, and do not hesitate to ask for a revision until the desired specifications are reached. The final sample is the prototype of the clothing product which you will release in the market.

With a good manufacturer, you will also get to get the approximate costing for your clothing product and eventually do the calculations for your estimated margin assuming different sales prices. Since you are on a tight budget, it is advisable to work hand in hand with the manufacturer to keep errors at a minimum and avoid lots of revisions. Each revision accumulates costs which may offset your budget in case the revisions become too many. The sample and costing process is a lot of work so that the costs are more substantial here. It is possible to get a custom sample plus costing done for USD300 (see reference at the end of this article), while you’re often charged significantly more. Make sure to check for good offers.

4. Starting Mass Production:
After the perfect sample has been created, you can now gear up and integrate the design for mass production. The most difficult problem when working with a limited budget is that you have to find a manufacturer that supports low volume apparel production, since you have to finance your later larger orders with a few smaller orders first. By working with the specialized small quantity clothing or textile manufacturing companies, you can realize that without having to pay a fortune per piece.

It is advisable for you to at least check the first production batch as part of your quality control program. Make sure each clothing unit is perfectly created the same way it was during the final sampling. In case you find some substandard products, inform the manufacturer to improve next time or to fix the issue if it’s a bigger problem. The mass production costs depend almost entirely on your product; however, even sophisticated pieces can be made for less than USD10 per piece even at small quantities. This leaves us with room for doing about 60 pieces of custom clothing assuming a budget of USD1,000!

5. Market the Clothing Line:
With less than $1000, you can't allot much money for your marketing campaign since it is now mostly spent on overhead costs, the design and manufacturing expenses. Fortunately, you have social media and your contacts where you can easily market your brand without having to spend a single penny. Create a website and social media channels for your brand and do most of marketing here almost for free.

You can also try connecting with fellow young clothing brands and help each other out through mutual referrals. Do not consider them as direct competitors, especially if you are confident enough your designs are unique and caters specifically to a target audience. Their customers can also be your potential customers and yet maintain a friendly and healthy competition between design ideas.

There is always a Solution even with Limited Budget:
$1000 are an absolute realistic amount to start your clothing brand. The capital could go a long way
with the right knowledge and by working with the right partners for your clothing business. As long as you know your designs will sell, your limited budget should not stop you from pursuing your clothing business goals.

One of the industries that operate in the on-demand manufacturing model is the textile industry. There are specific periods during the year where the demand for textile products is very high. Most of these products are manufactured on demand, indicating a huge need for temporary warehouses. Here is everything you need to know about temporary warehouses for the textile industry.

Advantages of Temporary Warehouses for Textile Industry: 
Some key advantages of temporary warehouses for textile manufacturing industry have discussed in the below:

They are cost-effective:
As a businessperson, there is no need to break the bank for a traditional warehouse, especially if your warehouse needs are short-term. The textile industry is one of the industries that does not require large storage spaces the entire year. A temporary warehouse is a perfect solution here, and it comes with the advantage of being cost-effective.

In most cases, temporary warehouses are modular. The major construction materials are steel for the walls and PVC paneling for the roof. The overall cost for setting this structure up is cheap when compared to building or renting a traditional warehouse. Get in touch with Smart Space experts and they can help you acquire one of these structures.

Easy and quicker to construct:
One of the advantages of setting up a temporary structure is that it is minimal or no ground preparation required. Most of these structures do not need a permanent foundation. On top of that, the construction materials are modular, meaning that installing them is quite easy.

Building a temporary warehouse can be done with your team of untrained workers. This can save you both time and money. Setting up a temporary fully-operational warehouse can be done under a week. Another advantage that temporary warehouses have is that they can be disassembled and moved from one site to another.

Temporary warehouses can be used for both short and long-term:
As mentioned above, steel is one of the materials used in constructing these warehouses. As we all know, steel is highly durable. Once you have set up a temporary warehouse, you can use it to address your immediate warehousing needs. You can then continue using the structure without having to worry about acquiring a permanent structure.

Is a temporary warehouse the right option for the textile industry?
Warehousing needs can arise at any time of the year and sometimes you are confused about what option you will go for between a temporary or traditional warehouse. There are several considerations you must look into including your budget and the cost, the length of time you are going to use the structure, how fast you need the warehouse, and where you want the warehouse to be located.

Considering all of the above factors, for an industry like textiles, one of the best solutions is usually a temporary warehouse. The structure is durable, saves you money, and can even be fitted with heating, cooling, and lighting mechanisms.

How to Calculate Knitting Production in Textile?
To calculate the knitting production in textile, you have to know some formula. In another article I have shared the production calculation of circular knitting machine. This article has presented some important formulas of knitting calculation with examples. Hope it will be very useful in your job profession.

Knitting Calculation Formula in textile
Fig: Circular knitting machine
Knitting Calculation Formula:
Some important formula of knitting production calculation have mentioned in the below:

1. Production in length,
= Course per minute/ Course per inch,

Or,
= CPM/CPI

Or,
    Number of feeder× cylinder RPM× time× efficiency
=…………………………………………………………………..
                                   CPI×36

2. Course per inch,
= Course per minute/production in length

3. Course per minute,
= course per inch× production in length

4. Stitch density,
= Course per cm/ Wales per cm

5. Fabric width,
= {(∏× diameter of cylinder× machine gauge)/wales per cm}

Or,
= Number of wales/Wales per cm

Or,
= Number of needle/ wales per cm

6. Fabric weight,
= {(Course per minute× yarn length per course)/ yarn count}

7. Needle number of machine,
= ∏× diameter of cylinder× gauge

8. Yarn length per course,
= Total number of machine× loop length

9. Production of single jersey machine in weight (kg) per hour,
∏×cylinder dia (inch)×cylinder RPM× feeder no.× gauge×stitch length (mm)× tex×60×efficiency 
=………………………………………………………………………………………….....……………
                                                           1000×1000×1000

10. Production of double jersey in length,
= Single jersey production in length/2

11. Production of double jersey in weight,
= Single jersey ×2

Production Calculation of Knitting Machine in Textile:

Example-01:
If machine diameter= 20 inch, feeder number= 90, course per cm= 15, machine speed= 25 RPM and machine efficiency is 90% then calculate the production per shift of a single jersey circular knitting machine.

Solution:
Here,
Diameter of machine= 20 inch,
Number of feeder= 90,
Machine speed or machine cylinder RPM= 25 RPM,
Machine efficiency= 90%= 0.9,
Time= 1 shift= 8 hours = (8×60) =480 minute
Course per cm= 15,
Course per inch (CPI) = (15/0.3937) = 38.10≈38 

So,
Production in meter per shift,
    No. of feeder× cylinder RPM× time× efficiency
=…………………………………………………………..
                                CPI×36

   90×25×480×0.9
=……………………….
          38×36

= 710.53 yds
= (710.53×0.9144) m
=  649.7 m per shift 

So, production per shift for single jersey circular knitting machine is 649.7m

Example-02:
Calculate the length in meter of a plain single jersey fabric at 16 courses per centimeter on a 26 inch diameter and 28 gauge machine having 100 feeders. The knitting machine operates for 8 hours at 29 RPM at efficiency of 90%.

Solution:
Given that,
Machine dia= 26 inch,
Machine gauge= 28,
Number of feeder= 100,
Machine speed or cylinder RPM=29 RPM,
Efficiency= 90%= 0.9,
Time= 8 hours= (8×60) =480 minute,
Course per centimeter= 16,
Course per inch (CPI) = 16/0.3937=40.64≈41

So,
Production in meter per shift,
    Number of feeder× machine speed× time× efficiency
=…………………………………………………………………..
                                  CPI×36

     100×29×480×0.9
=………………………….
             41×36

= 848.78 meter per 8 hours,
= (848.78×0.9144) m
= 776.12 m per 8 hours

So, production for this calculation stands at 776.12m per 8 hours.
