If you want to do all black, this is my suggestion. I love the one pieces that have been coming out lately, and I always love a big beach hat. Though it's not a beach bag, this Gucci arm candy is just as good!
If you're into browns, golds and bronzes, then you're likely to fall for this set more than the other two. I like an oversized cover-up but I don't like to to be solid. A pattern is much more fun and appealing.
Last but not least, if you're into color try this bright red one piece and spice it up with a little some animal print. The Betsey Johnson beach bag sets the look off, without it it'd be boring.
