Knee length long top. 2.) Long sleeves till wrist. 3.) Does not reveal the shape and skin of the body, especially private parts (Breast/Butt/Pelvis). No open-back. 4.) No cleavage. 5.) Not tight.

A winter season t-shirt. 3.) A fall season t-shirt. 4.) A sweater. 5.) A formal/party-wear top. 6.) A woolen coat. 7.) An insulated, wind-shield, waterproof, winter coat. In short, I would need a total of 14 designs, 7 for men and 7 for women, one for each category listed above. My target customer is western youth.

The final designs should be in an image format, with details, such that I can send it over to the clothes producer and it explains to them all that they need: dimensions for different sizes, fabric specification, color, stitching patterns, etc.
