According to Charli XCX’s latest Instagram post, one thing’s clear: Brat Summer 2.0 is here, and it’s hot. The megastar shared a mirror selfie giving fans a behind-the-scenes look at life on tour, but it was her bra that really stole the show — specifically, a pink U-plunge bra from the brand Fleur du Mal. This ultra-flattering lingerie must-have isn’t only suited for three-time Grammy Award winners, though; it’s also a top-rated favorite amongst everyday customers of all bust sizes, garnering rave reviews for its wearability and push-up capabilities.

Fleur du Mal’s Le Stretch Micro Seduce U-Plunge Bra promises to feel like a second skin — a rarity in the world of bras — and, based on reviews, actually delivers. It’s part of the brand’s Le Stretch Micro collection, which was launched last year and is marked by a soft microfiber fabric that boasts four-way stretch plus a “barely there” feel that makes it great for long, sweaty hours on stage or long, air-conditioned hours in the office (depending on your life’s calling). Since comfort is a top priority when it comes to bras and underwear, it’s no surprise that Le Stretch Micro’s top hits have gotten so much traction. Now also earning the Charli XCX stamp of approval, the collection’s Seduce U-Plunge Bra features silky, adjustable straps; a racerback style option; moisture-wicking, UV-protecting properties; and a push-up design that offers ample support.

Color-wise, Charli XCX’s choice of undergarments is a stunner through and through. The “Pink Cadillac” shade, which Fleur du Mal unveiled in March 2024 as a nod to the pink that’s been trending since the release of “Barbie,” has more vibrancy than the traditional, ultra-pale pink that bras and underwear are typically sold in. Those worried about visible pops of color need not be: The bestselling bra’s minimal coverage (can we talk about that curvilinear design and plunge?) will serve you well even with low-cut styles, like that halter wedding guest dress you’re going to be pulling out of the closet in the next few months.
As many shoppers can confirm, finding a bra that’s sexy without neglecting comfiness is no easy feat, making the Fleur du Mal Le Stretch Micro Seduce U-Plunge Bra a godsend. “This bra is such an interesting cut, but it really works under clothing to provide nice push-up action and extra shape. It’s also true to size. Highly recommend!” wrote a customer who purchased it in a B cup size. Another buyer added, “I’m a 36DD at a minimum. And I stay in this bra; other plunges I fall out of, but this I stay in.” A bra that can push smaller busts upward to grant more definition, whilst also serving larger cup sizes? That’s a win in our book.
Aside from all the summer dresses with plunging necklines you’re bound to flaunt this season, warmer temperatures also bring along a slew of itty-bitty tops that might’ve once made you feel intimidated: based on their incompatibility with most bras. Fleur du Mal’s Seduce U-Plunge one is not only accommodating to these airy styles but also lightweight itself. Summertime will feel as chic as ever with the bra’s roster of hues beyond the Charli XCX–preferred one, like the classic black and the goes-with-everything tan — both recently restocked after totally selling out. While there’s no “Brat Green” option yet (Fleur du Mal x Charli XCX collab when?), the crowd-favorite bra does come in a bodysuit option to channel your inner cool girl.
Fleur du Mal hit the ground running in 2012, leveraging delicate and sophisticated fabrics across its lingerie, ready-to-wear selections, and recently added swimwear. Knowing exactly how to mix sexiness-plus-sophistication with cheekiness and whimsy, the brand has attracted quite the fan club over the years. Card-carrying members include Rihanna, the Hadid sisters, Margot Robbie, Addison Rae, Kylie Jenner (with her Knicks-themed All Star Demi Bra officially available to shop), Ana de Armas, and many more A-listers. Even Charli XCX, this year alone, stepped out in Fleur du Mal three whole times: in the aforementioned Instagram post, her “party 4 u” music video (wearing Fleur du Mal’s ivory-hued Molded Luxe Triangle Bra and Luxe High Waist Panty), and also during a photoshoot for W Magazine’s January 2025 cover (Charli chose the Molded Luxe Triangle Bra in all of its silky glory for this occasion as well, albeit in black).
If there’s one parting message we want to convey about Fleur du Mal’s Seduce U-Plunge Bra before you take the plunge (no pun intended) and buy it for yourself, it’s that this clothing staple is a unicorn. Supportive, über-flattering, and incredibly comfortable based on all that stretchiness, the bra will make a world of difference in terms of feeling and looking your best. And, when it comes down to the wardrobe essentials you need to shop in 2025, this just might be a more worth-it investment than anything else in your bookmarks tab.
You’ll thank us when you’re b-b-bumpin’ that beat this summer, with the Fleur du Mal Le Stretch Micro Seduce U-Plunge Bra making you feel on top of the world.
