I like my Jovana, nice proportions (I prefer a small back and a thin waistband) but, as the previous poster mentioned, it does get complicated selecting all the alleged customized features. And the price is really ridiculously high. The JS bulge is good for something sluttier. Really, the very best thong ever was from a company called Gazelle, which also had great speedo-but-way-better-and-sluttier briefs. But, sadly, no longer in business.
Agree with the recommendations so far. I would also highly recommend Fireboy (fireboyunderwear.com). Great pouches, awesome fabric, lots of styles and customization!
I make all of my swimwear including both thongs and gstrings. As for underwear I make a lot of my own gstrings but usually buy my thongs from Amazon. There’s a ton of different ones on there with some great style and quality.
