A bra top is one of those trends that emerged on the catwalk and was then forced upon many teenagers by the means on TopShop, I got caught. Of course it's an impractical and fickle trend by I really like it and wearing it under see through blouses is a good wat to use in Autumn. The key to not looking like a street walker is to keep it casual (not exactly what I'm demonstrating in the photo). Putting a skirt, tights and a cardigan/blazer with it is your best bet. Also avoid heels to keep it on the right side of sexy.
