I've got 4 underwear drawers, this is just my thong / G-string drawer, over 100 here. (Sorry can't post the picture as the upload folder is full)
About half are name brands like Gregg Homme, Cocksox, Good Devil, Epidous, Daddy, Daniel Alexander, Andrew Christian etc, but recently i've found some great thongs on AliExpress. I've started to collect thongs of all sorts of materials, Ice, Silk, Hyperstretch like Gregg Homme, some mesh, see through, a few in lace, some with side clips.
The other drawers are almost 100% bikini briefs, One draw is just for Ice Silk, another for mesh and lace and the last drawer for undies that I probably should get rid of but can't bear to.
