Screen Printing Techniques
It's a saturated market, so designs that are similar to what is already carried in major retail stores are not going to be well accepted, especially when mass produced Screen Printing Techniques impact the price. People will not pay a premium for boutique wear when they have seen something similar in big chains for a lower price. If your designs are not unique, be prepared for a lot of rejection.
