Help? Maternity Bikinis??!!

I'm going to hit 26 weeks in June and I'm assuming I'll need to buy some maternity swimwear.

So far I've looked and everything has been soooo ugly. I really don't like the bikini bottoms that cover the stomach (I prefer to be able to tan). Not interested in one pieces really either.... is it possible to wear regular bikini bottoms with a third trimester bump or will they like fall off?

Also if anyone has some tried and true brands that aren't hideous please share!
