To Two-Piece or Not To Two-Piece

OK I am struggling with something (actually kinda shallow) but struggling all the same. I would love your opinion on the matter and please be honest; am I over thinking this?

We have a strict NO TWO PIECE bathing suit rule for our girls. We decided this when they were very young and the thought of our sweet toddlers walking around in a triangle bathing suit top made us cringe. Then as they got older the thought of my kiddo walking around in a two piece with all the sick people out there made me physically ill. I am sure everyone is thinking I am crazy but seriously they are little girls, they are supposed to be running, jumping and playing in the sand and water and NOT worrying about anything showing or being modest with a "to short top." So that's not changing. Case closed.

My dilemma is this; I have ALWAYS worn a two piece. Dan and were talking about our up coming trip to Hawaii & the suits I was looking at on line. Dan said,"honey, do you think its OK for you to enforce the "modesty" one piece rule on the girls and you continue to wear a two piece?" hhhhhhmmmmmmmmmmmm...............................so ever since then I have been struggling with the thought that maybe I should not be wearing one either. I mean obviously I am not flipping down the beach exposing my "stuff." So I ask you, whats your opinion on this topic?
