When it comes to underwear, nothing quite lives up to On Gossamer’s sheer mesh pant collection Light as air, invisible under clothes, trimmed with a delicate picot edge and sexy in its simplicity, it has been an On Gossamer essential for years. That’s why the On Gossamer Mesh Hip Bikini 4 Pack is such a great holiday gift. In four great colors fitting S-L, I hope there’s a pack in my stocking this year! I already own a chest full of these panties. a longstanding signature key item.
