OMG OMG OMG OMG OMG OMG?

Ok so yesterday I was at my friends hot tub party (we live in Palm Beach Florida so its not that cold) and we were all goofing off and playing stupid pointless but fun games and I guess I was jumping around a little too much because my bikini top flew down and I wear a size 34c so I'm pretty big considering I'm 13 and in 7th grade. All the guys were hollering and staring but my almost-bf (the guy I really like) was there too and he saw and now I cant even look at him! but thats not the problem the problem is that I stayed home from school today just becuase that was SO embaring. I'm not the type of person to change myself for anyone but I just couldn't make myself do it. I know the guys wont tease me or anything at school, they're nice and they get over stuff pretty quickly plus we're all friends so its not a huge deal. But on the other hand, the guy I <3 saw my and now idk what's gonna happen with us...:(
