As we are designing more and more clothes, our "shops" start to become too busy, with all the clothes in a vertical column and mixed (pants with shirts etc).
My suggestion is to be able to split our clothes into t-shirts and shorts, and then inside those, also by "design lines".
Then the customers could go directly to t-shirts or shorts depending on what are they looking for, also to find them sorted by colors, styles etc defined by the clothes company owner.
Another option that would be cool is to allow the shop owner to move up/down the designs, to have the best ones at the top.
For example, i have just created the "skull series" and i would like to offer them separated from other "design lines" in my shop.
