Swimsuit Help!!!

I'm pretty insecure in a swim suit nowadays. I'm short and have a curvy figure but not very large boob or cleavage. So Ive been SEARCHING everywhere at stores and online for a swim suit that doesn't show my entire tummy and also has a push up underwired top. I haven't had any luck. I'm also only 20 I don't want some granny suit. If anyone is willing to help a girl out with this impossible search I'd greatly appreciate some links to swimsuit I can purchase or ideas on where to get one! Thank you all SO much!
