What theme should I use for an e-commerce store/

Hi all,

I have installed the marketPress plugin and my understanding is that I can use it with any theme in WPMUDEV. Is that correct?

I am trying to set it up using FrameMarket but I do not like the storefront. I would like something much closer to a regular e-commerce store and I do not know if I can achieve that using this theme. For instance, can I achieve anything like this: http://www.net-a-porter.com/ or http://www.shoescribe.com/? What do I need for that?
