Sorry but until you lose some weight you are not ready to be wearing one to any party. Just my honest opinion.

i too have a white sink and a whale!

Do a core workout everyday and youll get toned and feel secure in your body

Go for it. You look fine.

Sure

be confident with your body, you need to accept yourself before anyone else can, if you are not confident enough, you could do a cling film wrap, and do sit ups, juts before u go out in your bikini, it really does make a difference
