As a guy, I don't know anything about Bras, but it seems like VS is just more widely distributed. I'm a huge fan of Maidenform underwear (bottoms), and really enjoy it when they come up in my underwear rotation. Their stuff is just so nice, so I hope they catch up with VS/Limited, but as of now, I think VS sells much more.
Color & style selection
