Size S. This suit is FABULOUS, I’m ordering more colors! I love that it’s a bikini, but gives such full coverage — such a dream for us as mamas doing all the things this summer with little ones. 🤎🐚 And this top is something I’ve had for yearsss actually. It’s such a versatile piece! I’ve worn it as a coverup and also out of as a top.. can’t beat it!
