I have a thing with changing bathing suits, unable to stick to one for very long. This is partially because the more variations you wear and the more often you change them up, the crazier the cuts you can get away with, without ending up with a potentially odd-looking tan line.
However, when in doubt, I always find myself returning to the Little Black Bikini. This one is from Ivy Revel, and has a little extra something to it - the sparkle gives it glamour without overdoing it and landing somewhere in Vegas territory. So what you end up with is a comfortable, elegant suit with a dash of mermaid vibes. Tis the season for mermaid'ing!
