Visualize your product by drawing your design ideas. Create a few sketches for different versions of your potential products and get inspiration from existing designs. Once you have developed a concrete concept, you can now move forward to the next crucial process.

The tech pack is the most important document on how to manufacture clothing. It is a design file which contains sketch and specifications of the proposed clothing product. The materials, trims and accessories which are going to be used for the product are also listed on the side. The tech pack is the standard file presented to factories and suppliers which lets them assess if the product is doable and ready for manufacturing. Clothing product design firms can help.

The next apparel product development process step requires you to determine all the dimensions of your product. Consider the length, width, height and even thickness of your clothing product. Create a variation of the measurements for different sizes (S, M, L, XL,...) so the manufacturing company will have clear set of instructions to follow for different variations of the product. You don't want manufacturers to assume measurements which you weren’t able to list.

You are at an integral stage of the apparel product development process once you are ready for sampling. You will work alongside the manufacturer to create the first version of your clothing product. This sample will become the basis for the final version of the product and this is where reiterations and modifications will be made to achieve the desired clothing product. Check your sample carefully!

We have reached the point where your simple idea is now brought to life. This is a big step in the clothing product development as we now reach the production line to manufacture the actual product based on the comments and feedbacks given on the product sample. You are all set for mass production depending on your budget and expected product demand in the market.

The final stage of fashion design and product development is quality assurance wherein you should inspect each clothing piece (or a certain share for large quantities) from the production batch and make sure they are all up to your standards and desired results. You don't to release subpar products as it would affect your company’s reputation. Wholesale clothing products are all expected to be of the same quality and this expectation is high for consumers and merchants.
