HANKY PANKY has been my underwear brand of choice from over a decade. I wear the original rise thong in cotton and find them extremely comfortable. The quality is excellent and if you launder them gently and hang dry they will last a loooong time. They have TONS of styles beyond their original and offer inclusive sizing in several of them. I usually order via ShopBop or Nordstrom but you can shop direct from the brand here.
