Build me a footwear and clothing designs -- 2

I am a developing clothing brand with a passion to develop something that will appeal to the customers. I want to produce t-shirts, tracksuits, sweaters, jackets, and sneakers, and also headwear, although for now, I need help with a design sample for sneaker shoes, jackets, tracksuit pants, and t-shirt, depending on their prices which will cost, then I will decide which one is going to be the first.
