We always suggest basing your Knix size right off your measurements in inches. You can find instructions on how to measure, plus our bra size calculator here.

All Knix Bras, Tops (including Bodysuits), Shapewear, and Pads are eligible for return or exchange within 30 days of delivery. That’s because we want to make sure you give your new Knix products time to mold to your shape and reach their peak comfort.

Do what you want to do in them and wash them as much as you like. If you find the fit still isn’t right, message us to get a personal fit consultation before returning for the right size.

Select styles come in sizes 28A-44H. We’re big believers in innovation, which means we’re always looking to expand our size range and further improve our products. Size questions or recommendations? Send us an email to info@knix.com.

Your new bra may fit snugly at first, but they’ll soon relax and mold to your body as you wear and wash them. We generally recommend wearing them for as long as is comfortable, then washing, and repeating this process 3 to 5 times to get the true fit.

Most Knix bras, including the Revolution V-Neck Bra and the WingWoman Contour Bra, are made with bonding technology designed to create a comfortable seamless feel and solid support without using an underwire. Most of our wireless and wired bras are made of a nylon and spandex blend.

Washing your wireless or wired bra is easy. For best results, machine wash on cold with mild detergent in a wash bag, and lay flat to dry. Always check the wash instructions on your specific bra though. If you’ve purchased the FreeFlex, make sure to hand wash it with cold water and lay flat to dry.
