We made the unsung wardrobe heroes you've been missing. The best basics—underwear, perfected. These classic mid-rise bikini undies boast just the right amount of coverage and a cheeky cut. With a tonal elastic band and soft trim, they're made from sustainable cotton jersey blended with modal for a smooth, light-as-air feel and second-skin fit (like they're barely there). You shouldn't have to think about underwear—leave that to US. We've thoughtfully engineered each pair to feel so comfortable you'll forget you've got anything on at all.

Reviews
Comfy and nice quality! As
"Comfy and nice quality! As someone who is newly plus size, the brands of panties I used to buy no longer fit my body well (even in my correct size) because the gusset is not wide enough. I did some research and decided to try this style by Universal Standard and I have nothing but good things to report! I will be confidently buying more styles from them now."

Nice undies
"Fabric soft and comfortable. Elastic waistband lays flat and stays put. I have several pairs now. These are the first bikinis I've worn in a decade! ( I also like the US full coverage undies)"

not the unicorn of underwear for me
"I love comfy cotton underwear and was exited to try these. I have a coupel of issues with the mid-rise bikini. First, there is more coverage in front than I need and I don't have enough in the rear. I find this odd. The elastic waistband doens't roll or collapse but it is too tight for my hips and distorts my shape. Maybe I needed to size up? also the side seams in the elastic are uncomortable when I am wearing leggings over them. I don't recommend these."

Liberates High Mid Rise breifs
"Love them, fabric, fit and all."
— Constance P. (5/5)
Comfy, but SO high
"Love the fabric and the coverage. However, I find the gusset wide and these are definitely not a mid-rise. I'm a medium petite (5'3") and had to size down to a small in these. I tried the medium, but there was so much extra fabric in the seat and gusset—and the rise was so high that the undies were visible under even my highest rise bottoms. The smalls are better, but still higher and wider than I need."
