I have to admit it does look a bit like lingerie to me, and looking at the website the tops of most the dresses look like lingerie, so I assume it is the designer's look.
I couldn't wear something like that, as another poster said, I would feel very exposed and cold!
But it would be good to see a photo of you in it, if possible, as I certainly don't have the figure for wearing something like that, so can't really picture how it would look on a real person, rather than in a staged set up IYKWIM
