Mr. Bee's parents live on the beach (they run b&b style cottages), so we will be spending a lot of time in the water. I surfed around for 15 min for some swimming suits that might address the boob popping out problem I had at the pool earlier today.

Polka Dot faux blouson one piece - loose shape hides the belly well and is quite modest.

Modcloth retro suits (high neckline + halter provides extra support)

J crew striped rash guard - then I'll really be covered and won't have to worry about sunblock

Feel free to suggest other options! I don't have much time to order one since I'll be leaving in 2 weeks....
