Modibodi brand overnight/heavy seamfree full briefs. One was worn once, the other was never worn. I purchased in two different styles but liked the other one better (not a high waist fan). The size is XS, I’m usually a small in bottoms, waist size 25 or 26 but I think period underwear should be a bit more snug. The liner goes all the way to the back, this is designed for overnight absorbency. I paid $29 each plus shipping, I’ll do $15 each
