As with other reviewers,I went with a size up from my regular size and I am glad I did. There’s no pantry line and they are quite soft and comfortable. For reference i am 5’6” 138lbs and bought a large.

I have tried a couple of different brands of wool bikini underwear and Unbound Merino is the best! They are lightweight, elastic doesn’t roll, silky soft material! I love Unbound Merino’s triangle wool bra also!
