I'm looking for a tshirt designer product to incorporate on a website. The desired result is that they would be able to design and submit (not put in a cart) to the design team. Can this plugin be used without woocommerce? We have no need for woocommerce or catalog integration at this time. 

Yes, the fancy product designer works without woocommerce, and customers can customize a product, and submit it to you first before a final order.
