im pretty sure this is the right place to post this...?

anyways, i bought a swim suit yesterday for camp. i needed a one piece
bathing suit because the camp im going to doesnt allow two piece suits,
and i bought it at the thrift store, seeing how i only need it for camp. so i
cant return it or anything. i didnt realize this until today, but the swim suit
doesn't have any padding. i dont mean paddin to make my boobs look
bigger, but padding so that my boobs dont show or anything. you know what
i mean? so my questions are:
1.) is it okay to wear a bathnig suit like that? im like a c - cup. well, that
and im not sure if i feel comfortable in a swim suit like that.
2.) if not, what can i do about it? without buying another swim suit.
