We used virtuemart for several years to create our online shop : http://www.chezfee.com
We're selling cute and kawaii products from Japan, Korea, China and also from Europe
The site is in french, but we can speak english, french, and chinese fluently, so don't mind taking a look / asking us questions if you need
We're thinking to make an english version but I personally have to take a look how to do it efficiently.
We did all the design and worked on the responsive version of the site, there are still some little imperfections but we're working on that (and will be releasing a more modern version later)
Comments here are greatly appreciated
