The boob window is the new trend in celebrity dressing [1] making waves this year, both on and off the red carpet. As early as 2022, the likes of Maya Jama and Rita Ora have been spotted in the look. The outfits often resemble halterneck silhouettes, although not all of these numbers boast a strap on each side.

Florence Pugh is the latest style icon [2] to give it a go, taking a funky, festival season approach. The 27-year-old "Don't Worry Darling" star selected two sheer, neon catsuits for partying at Wilderness Festival [3] in Oxfordshire with friends, including the bright green stocking jumper she spotlighted on her Instagram Stories. Pugh played up the hole at the chest by affixing light-up bracelets to her strappy pink bikini worn underneath. She accentuated her waist with an iridescent bumbag and capped off the ensemble with statement accessories such as a feather-trimmed cowboy hat, oversize furry blue sunglasses, and several chunky rings.

Pugh's outfit is not unlike many of the others we've seen on the likes of Kendall Jenner, who showcased her take on quiet luxury [4] in a grey Bottega Veneta midi while spending time in Paris; and Chloe Bailey, who attended the Culture Creators Innovators and Leaders Awards brunch in June rocking a mixed-media ombré gown from Harbison Studio that just might take the cake for most skin-revealing boob window to date.

While it's easy to find similar details on going-out pieces stocked at Revolve and Meshki, there's simply no denying that Hollywood A-listers will bring the heat when it comes to boundary-pushing boob window dresses curated at the hands of their stylists. Ahead, see the best instances of the trend so far, then review all the champions of bold bum cutouts [5] and the visible bra [6].
