Started out purchasing these for my trans son to get them started on wearing undergarments, per their request. I ended up liking the way they fit after trying the large out! They are very comfortable. Importantly, they don't "ride up" under my boobs. I've got a bralette, straight up soft bra and racerback. I ended up with the bras because the large didn't fit them, so I kept the bras for my use! I am hoping the XL will fit them - I just ordered one. We've got three pairs of the 4.5 Tencel trunks, and they find the underwear very comfortable. The pricing is comperable to other stores, so it's a win. Fast shipping too! Product is packaged well.
