Women's Intimates

We get it. The world of women’s underwear is vast and overwhelming. While at the same time, it feels like there’s nothing out there to meet all of our needs. While there’s definitely a moment for underwire bras, push-up bras, bustiers, lace bralettes, and lace thongs, sexy lingerie doesn’t always have to be ornate. Sometimes, we crave decadence in the form of practicality cut from luxurious fabrics—simple but beautiful base layers to build our everyday looks around. That’s why we designed our most intimate collection yet with this (and you) in mind.

Meet the unsung wardrobe heroes you’ve been missing—underwear perfected. Our collection of undergarments may be small, with just three styles in three colors, but it’s mighty. These understated undies look simple (and they should), but they were designed to be a force in your styling arsenal. That’s why we’ve called them UltimateS. They’re the ultimate intimates fit for all of US.

As the industry leaders in elevated everyday essentials for everyone, we wanted to make what’s been missing: inclusive underwear, offered in sizes 00 to 40. Engineered by a team of dedicated experts with all of the details that make garments last a lifetime, these will feel custom-made for you—because they were. It’s about time we offered hero wear from the inside out.

Your number one problem became our number one solution. The UltimateS underwear collection simplifies your search for everyday undergarments. With all that’s out there—think a bikini panty, a high-rise thong, a low-rise thong, briefs, hipsters, boyshorts, tights, bodysuits, and beyond—we’ve narrowed the selection down to three staple styles. So get ready to cross these must-haves off your wish list.

The perfect high-rise brief, high-rise thong, and mid-rise bikini are here to make every day better. These aren’t your average microfiber panties, they’re made from a sustainable, supremely soft cotton jersey blended with modal that feels soft and light as a whisper against your skin. They will move with you without riding up or digging in. They have the perfect amount of stretch, a comfortable elastic waistband (with just the right width), super soft trim (instead of restrictive lace trim, for example), flexible leg holes (instead of those that cut in), and a considered gusset that’s graded per size (coverage for all of US, as we are).

Whether you choose full coverage with our high-rise brief, cheeky medium coverage with our mid-rise bikini, or no backside underwear lines with our thong, they're antimicrobial, moisture-wicking, and breathable so that you can count on them all day long. Hopefully, you'll forget that they're even on. You shouldn't have to think about underwear. Leave that to US.

A two-year development process led to three perfect undergarments that you'll love forever. Not only did we meticulously decide which details to include and why, but we also wear-tested every style ourselves to make sure they fit, felt, and wore beautifully over time. You'll reach for these no-frills and no-fuss staples again and again because of their ease and unpretentious perfection. They may not be your typical sexy lingerie styles, but they're sexy because they're real. Our team of real people wanted to create real underwear for real life.

Pretty, pared-back, practical, perfect—the ultimate everyday underwear promising supreme comfort, luxurious quality, and exceptional fit for sizes 00 to 40. We don’t just want you to look great in our outer layers; we want you to feel confident underneath it all. It’s what’s on the inside (of your outfit) that counts. These are the best base layers, the solutions to problems that haven’t even happened yet. And won’t. Three styles, three colors, infinite reasons why.

Though the thoughtfully edited selection addresses what we all need right now, we want to expand our selection to include many more intimate styles for every day (and beyond). We hope to introduce the ideal underwire, demi, push-up, strapless, and t-shirt bras. And wire-free bra options like bandeaus and bralettes. Plus, the best of the best sports bras to wear with the athleisure styles you already live in and love.

We're always working toward ensuring unprecedented accessibility in the marketplace and want to see all of US wearing what we want without compromise. Sure, we've introduced the most inclusive luxury outer layers, but we knew it was time to go deeper. And there's so much more to come. We're dreaming of bras and undies to wear under all of our hoodies, sweaters, long sleeves, jumpsuits, rompers, tees, and camis. Imagine our favorite styles, from silk dresses to plunging scoop necks and V-necks to sleeveless and racerback tank tops, paired with the perfect undergarments to help them shine. Keep your eyes peeled for new arrivals soon.

Until then, delight in the three second-skin styles of your dreams. They’re here and waiting to be a part of your real life. Try one of each (or three of each!) and see that these key styles are really all you need and what every woman wants to be wearing. Oh, and they pair perfectly with our best-selling Foundation base layers in a shared palette of elegant neutrals. Both made from a sustainable cotton jersey fabric, UltimateS are smooth-as-silk thin while Foundation is subtly ribbed. Either way, they’re quite the match. Choose your favorite underwear cut and Foundation style to make your new favorite lounge-at-home outfit or comfy braless undergarments to throw sleepwear or sweats over. The best base layers are better together—made for you and perfect for each other.

While we're on the topic of Foundation, we love to wear these out as well (as hero pieces) and don't think of them as pure under-layers in the same way as UltimateS. They’re truly versatile. What else pairs perfectly with UltimateS? Any high-waist denim style from US. Actually, we designed our underwear to have a similar rise as our jeans and sit at your natural waist—not just for coverage, but so they fit beautifully under the waistband of our high-rise denim styles. You won't find a rise like this anywhere else. We know you know—you’ve been looking, and asking, and so we’ve answered. We were already on the same page. Our idea of ultimate intimates includes an ultra-high rise. Opt for underwear that will take you higher with the rise you've always wanted.

UltimateS will become your closest companions and move with you through everyday life, from sunlit mornings to quiet evenings and everything in between. Our most intimate collection yet is for your most intimate moments. Don’t get intimate with just anyone. Turn (un)dressing into an enjoyable personal ritual. Your day should start and end with a simple pleasure: Your UltimateS.
