I find Aerie thongs to be super comfortable and fit well through the waist band and the gusset on my body. Most of these are low rise thong options, but I did include one high rise thong that I have in my underwear drawer. The type of fabric varies based on the style. Some are sexy while others are more “invisible”. I usually wear an XL in Aerie thongs. LTKunder50 LTKcurves
