Sexy sexy thong

Normally I only buy gstrings but I figured since it matches with the sieve non-wire bra, I had to buy it. It’s super comfy and sexy. I got an XL cuz I’m normally a size 12 but it’s actually a bit big on me. I love the mesh too, it’s sexy but not in your face sexy.

So comfortable!

I’ve been on the hunt for a bra that “feels like nothing” and this is the closest I’ve come. It’s super light weight, supportive, breathable, well-made and you can barely feel it. Highly recommend!
