I'd like to know your opinion about a piece of clothing I own. Here it is:

My god, since when do I look so fat from behind??!

What I'd like to know is: do you think this is lingerie or a cami?

I bought it at Jean Bleu, which is absolutely not an underwear store, but my boyfriend says it's inappropriate even to go clubbing, and another guy friend pretends it's lingerie! I know, this cami is not for everyday wear, but still, when I saw it at the store, I thought it was so beautiful that I bought it without thinking how I would wear it. I could throw a vest or cardigan over it, but still...

The tissue seems too delicate to be a simple cami... and I don't even need a bra under it (I have one in the pictures), since it squeezes my boobs so much that they hold by themselves LOL.

What would you do with this?
