These GOCBOBO tights are that perfect 'barely there' layer you want under dresses and skirts. They're 0 denier, which is about as sheer as you can get, giving you a smooth, matte finish that looks like your own skin but better. The seamless construction means no annoying toe seam or panty line - they really do feel like a second skin. They've got good elasticity for shaping and light tummy control without feeling tight or restrictive, so you can move freely all day. The material is breathable and made with a special knit so they're less likely to run. I wear them to the office with a skirt suit, on a date night with a little black dress, or even casually with a tunic. Size reference: fits best if you're between 5'2\ and 5'9\ and 88-132 lbs. They just make your legs look polished and put-together. A total wardrobe staple for looking elegant without any fuss.
