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 a 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
The perfect pair
"Love these undies, so comfortable and smooth! They fit great, and the fabric is breathable. I’ve purchased every iteration of these undies and love that they have multiple coverage options. I only wish they had them in more colors and prints but they’re super comfy, simple and cute"

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."

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."
