Boob weight?


Sooo I got this swimsuit online and it fits my body perfectly except my boobs are too big for it. It’s a tankini top and my boobs just suddenly got bigger idk I’ve been the same weight and I’ve not lost or gained anything. Anyways does anyone have any good tips on how to lose weight in your boobs/ arms area? Also I don’t want to send the top back for a bigger size because I’m worried I won’t have it back in time for vacation. And I can still wear the top I just want my boobs a little smaller so they aren’t out in everyone’s face.
