Body shaming?

My brothers girlfriend brought me some dresses to try on for my friends party and I put on this white bodycon with an open back, mesh v neck, and a halter neck.

I was showing off on Snapchat to some of my friends because I fell in love with it and it was super cute on me. And my “friend” responds by saying “a bit booby” and after I was telling her how my guy bestfriend said it looked nice she tells me “of course he did you look like a hooker” this was coming out of the girl who got me to trust her after she dated my ex boyfriend and claimed to be my bestfriend...
