Absolutely. You can find our full sizing guide on each product page. Our styles are made with seamless, stretch-adaptive fabric that moves and conforms to your body — so fit feels forgiving and flattering across a range of sizes. Still unsure? We're happy to help, just reach out.

Our seamless fabric is designed to stretch and adapt to your body, so you'll find it more forgiving than traditional intimates. If you're between sizes, we recommend using your true intimate size for that signature second-skin feel, or sizing up for a softer, more relaxed fit. Still not sure? Contact us — we love helping you find your perfect fit.

To keep your pieces looking and feeling their best, we recommend hand washing in cold water with a gentle detergent and laying flat to dry. Avoid the dryer — it extends the life of your seamless fabric significantly.

UNDAE was designed with a specific problem in mind — eliminating visible lines and camel toe with a seamless concealment design built directly into every piece. No inserts, no workarounds. Just confidence, built in.
