My favorite swimwear brands are Vix, Mara Hoffman and Zimmerman. They all have great bikinis and one piece options that aren't matronly. I have some Victorias Secret bikinis as filler, they're pretty inexpensive and I like how there are so many cut options. But VS quality isn't that great. Honestly, take a look at Vix. They have a great sale section on their website. Shopbop carries them too.
