When we saw Kristin Cavallari's Instagram shot [1] 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 [2] 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.
