There's something so chic and glamorous about a simple one-piece. I never really gave them the time of day before having babies but I've grown to love them. Especially with two May babies! I prefer ones with ruching and a flattering neckline that will never go out of style. This summer I bought the polka dot one below (on sale!) to ease back into swimsuit season with a two month old!!
As for cover-ups, I like something neutral that can double up as a dress with sandals or flats. Great to throw on if Will and I get to sneak away for a late lunch or cocktails at the beach!!
