Wearing A Bikini...

I'm going to the beach for a get away trip with my sisters in a few weeks and I'm having a hard time deciding if a bikini will be considered "appropriate". Half of me cares what people will think and the other half of me is like, I've always worn a bikini so why the hell wouldn't I now!? My stomach isn't huge yet and I don't think it'll grow too much over the next three weeks.
