Purchase the fabric. 4. Design a label for your clothing. Create a catchy logo that appeals to your target market. 5. Offer to design outfits or even prom dresses for your friends. 6. Wear your creations to school/work every day. 7. Partner up with a school club when they do a fund-raising sale and offer to donate some of your outfits to be sold. 8.
