The most important part for any sample request is the hand over from you to us. The more you information provide the faster and easier (& cheaper) it will be to produce the samples/collection that you are after making. This can mean you providing us with the real shapes to copy, or web links to others designs with notes on changes (this works particularly well for active & swimwear) or spec sheets and lastly line drawings which are our least liked ways to work from. We charge 2 X estimates wholesale for simply designs and if more complex an additional $50 per style that we hold as a bond until the order comes in when we credit you back.
The time to make samples is not easy to speak on unless we can see the styles you want us to make for you. Normally for simple bikini around 2 weeks and then up to 4 weeks for printed motifs on fabrics to be used.
