Hi have a couple swim thongs from Charlie - they’re outstanding and perfectly cut. A thong friend of mine sent me this link...i don’t know how or where to wear it unless you’re doing it for your lover and its going to be taken off quickly...but it does look like a ton of fun to wear (at least for me!)https://www.charliebymz.com/collections/the-leather-collection/products/thong-harness-2
I have several Charlie thongs and they are pretty good but not perfect. The pouch cut if kind of wide and not overly stretchy so they can be a bit unaccommodating but still fit great and sexy. I also have a Charlie swim thong which is amazing!
