Universal Standard UltimateS Mid Rise Bikini

UltimateS underwear are final sale for quality assurance purposes. If you have any questions, please refer to our size guide or reach out to US.

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.

Why UltimateS?

• The elastic waistband has a comfortable width and sits flat without cutting in.
• The classic rise is comfortable and secure.
• They’re lightweight, breathable, antimicrobial, and moisture-wicking.
• The generous gusset width is graded per size.
• The soft and stretchy trim allows for flexible leg openings that sit flush without digging.
