I think you look great! Maybe it wasn't the right costume for a party but why does everyone have dress slutty for Halloween?
My theory? Halloween makes it socially acceptable to dress up like a slutty policewoman or nurse. People don't seem to realize that wearing a racy costume in the bedroom on non-holidays doesn't make you a brazen hussy.
But what do I know. My favorite costume in recent years was Tom Skerritt from Top Gun, which involved a flame-retardant flight suit and a mustache!
(To be fair, I liked sexy costumes in college, but that was back when I liked sexy outfits every time I went out.)
PS - I think the costume is cute, and the guy who said you looked like his grandma was an asshat. Even if he thought it, it's not cool to say it. It's not like he speaks for the world as a whole.
You know what I also think. There are a lot of women out there that wear things that are not appropriate for their body and not only look sexy skanky but street walker slut. I saw a lot of them last night.
I have a stretch marks on my bellyand no butt but you can bet your ass I'm not going to wear something that displays exactly the parts of my body I don't like.
