I got a couple of one piece maternity suits at Old Navy for reasonable prices - they've got the ruched sides that do an excellent job of making an awkward body look perfectly fine (and make a bigger bump look GREAT), I'll be wearing them through the postpartum period too.
Lol I'm 7 months and I hate looking at my belly and it is clearly a preggo bump. My bf just bought me a new 2 piece though, and even though I feel awkward as hell wearing it, it's really cute. It's really tight though bc I still bought a small so I could wear it after birth and I'm just afraid to undo and retie it to fit better bc I suck at tying stuff.
Two things...you either just 'own' your bump and show it off no matter what you think or for a little I wore a cute loose fitting tank over the bathing suit. It'll only be a short time of the awkward stage lol.
