Saggy belly....keep it covered with a one piece.
and for all those moms out there who wear real tiny swim bottoms when your bottom is big, it's time to size up and add a little swim skirt to big thighs and rump.
See LandsEnd.com for their "perfect swim suit finder." It shows lots of bodies and gives great ideas on how to look stunning---but ladies, you got to pick the right suit.
If you go to the beach, the community pool, a neighbor's pool party,... I would encourage everyone to be sensible and dress modestly. You really do look better when you make good decisions instead of just flaunting your body. I disagree with the poster who said flaunt it.
My opinion: if you wear your suit in your own back yard and that's it, then go for whatever you want. If anyone other than immediate family sees you, then make a good decision. The right clothes give you self confidence and that shows to everyone you meet!
