Found: Kristin Cavallari's Perfect Maternity Swimsuit

When we saw Kristin Cavallari's Instagram shot of her and her young family strolling to the shore, we couldn't help but stare at her suit! The strapless one-piece was supersexy, thanks to a shredded back, showing off some skin while covering up a burgeoning baby bump (Kristin's expecting baby No. 2). For expectant moms who don't love the idea of rocking a bikini while pregnant, this suit could be the answer — Kristin agreed, calling it "the perfect preggers bathing suit" in her photo caption. The strapless swimsuit with a sexy back is actually an old styling trick for her; she wore a similar black style while on a Mexican vacation nearly two years ago.

The style Kristin's wearing isn't marketed as a maternity piece, but it's a smart buy for any moms-to-be who want to keep their bumps under wraps. Whether you're expecting or not, consider making this your one luxe swimsuit investment for the upcoming season.
