As much as it pains me to admit it, I don't have any spring break plans this year—it's quite a bit harder to schedule a getaway in adulthood than it was in my college days. Blake Lively, however, is living her best vacation life right now. And thankfully, I can live vicariously through her Instagram photos, which racked up nearly 5 million likes in less than 48 hours. 

In one photo, Lively posed poolside wearing Madewell's Cinched Cutout One-Piece Swimsuit ($80). Her exact swimsuit is shockingly still in stock, but I have a feeling it won't be for long. Now that it's Lively-approved, it will start selling like hotcakes. The best part? The suit comes in a range of sizes( XXS to 4X) and even has special sizes for those with long torsos. Genius. Scroll down to shop Lively's black one-piece swimsuit by Madewell.
