I bought a three-pack and as soon as I tried one on I had to get another three pack. These are now my go-to underwear.
It is very unusual for me to give a review for anything let alone a thong. I'm a man and pretty big down stairs and these hold me in place so well I forget that I'm wearing them. I've been a fan of thongs most of my adult life and the only thing I can say negative about these is the cost but if they hold up id buy a whole drawer of them without any question. I wish I'd found them sooner
I wear a size 4 in pants, 5’5” and 115 pounds. The size listed as Small -size 6 is way too small for me. Medium fits pretty well but even that size is snug. Order carefully because they are not returnable. These are great underwear once you get the size right.
