I bought this body con dress from ASOS about a year and a half ago, and because I always saw it as a formal dress, never really wore it! It has a low back and front, and for some reason none of my bras would successfully go with it without pinning and general annoying-ness. The other week I thought I would try it with a plain white t-shirt beneath it to see if it suits a day look, and it's great! Suffice to say I'll not be letting it sit on a hanger for so long again.

I would have teamed it with some dressier shoes but as I'm away these are my only option. That and I never seem to take them off nowadays!
