These faux wrap pants have a tie front that brings the panels together and the back is a stretchy smocked-like elastic. Size 1 considered a small in Billabong’s chart, but fit is more like a medium and can ride high on waist or at the hip, depending on your frame. Loose and flowy regardless. Although it’s a mock-wrap the leg panels are entirely open to the hip so makes for a super sexy “up-to-there” leg when walking or in the slightest breeze. Great as a sexy swimsuit cover with slides or thong sandals, but easily dressed up with chunky heels and a loose tunic for evening resort wear. Impossible to wrinkle - the ultimate packable piece. The fabric tag is gone, but it feels like a rayon/cotton blend. I’ve always washed it in cold delicate and hung up for a quick dry. waist 14” across lying flat to 20” across stretched inseam about 30”
