Answer:
What you could do to improve the clothing is make it less revealing. A lot of clothes these days are too revealing and could use more cover on the body to be more modest. For the men's clothing you could make it more formal wear and appropriate for wearing outside as a casual atire. Don't include any words on the clothes but just the designs. For Women's clothes, make it less revealing and more modest (as suggested above) and chose simple yet attractive designs and once again no words.
I hope this helps you!
