These underwear are amazing for wearing under fabrics that reveal unsightly lumps and bumps. The fabric inside is "grippy", keeping them in place. Perfect length for wearing under golf and tennis skorts. Up to par with the Wacoal name. They aren't cheap, but totally worth feeling confident wearing them. The only thing that isn't perfect it that I wish they came up just a little bit higher to my natural waist, but overall they are AWESOME. They don't roll down at the waist, or up on the thigh openings.
