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!
