Anyway, I'm typically in the same boat. I wear over-sized clothing becuase 1) it's comfortable and 2) I'm trying to hide my shape and size (much to hubris2's chagrin).

Anyway, wear what is comfortable and what you think looks nice. Yes, size in itself should not be an issue. Maybe you and I should go shopping someday :). We could each find one outfit that flatters, that promotes and helps our self confidence and makes us look sexy (long as it's not lingerie) LOL.
