I want to launch a "Express Buy" button just under a product picture. The idea is to avoid one click, the one that goes to the product card. 
I want this to go straight in to my user's shopping cart. When you see the category page with all the product pictures, I want my customer to select the size and color and click on a "Express buy button" .

The issue is that I'm selling clothes so there are different sizes and colors. So I want to know if some brands already do it or if it is technically practical or not.

**This is something like what I had in mind:**
