Under.me sells underwear, and is one of the most innovative and sexy ecommerce sites we have ever seen. Clean and uncluttered, made up of simple blocks, the entire shopping experience takes place on just one page. The product selection menus are nothing but icons that communicate instantly and exactly what type of product you should expect.
After you add a product to the cart, a simple pop-up slides up from the bottom, subtle but obvious, ready for you to checkout. But only when you are ready.
Overall, a great user experience.
