Looking for product/tshirt design plugin or theme

I have an existing store (woocommerce). I want to add a plugin or theme so my customers can design their own tshirt or coffee mugs etc. (Mainly tshirts). Currently using the storefront theme fyi.

Have researched several but looking at some of the comments I’ve been a little scared off because looks like support isn’t the best for some.

Looking for something simple– preferably where customer can design something and submit for approval before purchasing.

Any ideas?
