The swim suit I have, which looks like the swimsuit Orema posted (the blue aqua colored suit), is black. And yes, it's fairly easy to get on. It's an one piece.
The other swimsuit I posted recently, the polka dot suit, looks like an two piece (swim dress top with matching panties).
I like both of them. Both look fairly nice. They hold their shape good, too. But I also like all the other suits posted too. They all look really nice, I think.
You might be like some or most of us here. I personally like to try the suit on first, to make sure it fits right. Good luck to you and hope you find one that you like and fits right.
