Bikini while pregnant?

Heidi
So my husband and I are going to Florida in March with our one year old and I will be 27 weeks pregnant. I have had to buy new summer clothes, but as far as swimsuit goes my husband and I don't agree. 
He wants me in a one piece all covered up, while I would rather wear a bikini and is still covering and not exposing everything.
I already hate wearing clothes on my belly this pregnancy and spend most time at home in a sports bra or with my shirt pulled up. 
Is it bad to wear a bikini while pregnant?! 
Opinions please!
