I want to start off by saying I am a 34" waist and got a size medium. It is a little tight, which is the way I like it. I would say the sizing chart is very accurate.
I love these! They call it a brief but really it should be called a bikini. I love the xcurve pouch! It is really wonderful. The fabric is very thin and stretchy. This helps keep the stitching and seams very thin as well. Bravo! It is really smooth and soft to the touch. I absolutely love the prints!
The logo on the waist band is a little poster boardy with the name all the way around. I don't mind it but I could see why some guys would really just prefer either one logo or none at all. That being said the waistband its self is perfectly adequate, good thickness, softness, and height. The light fabric in conjunction with the full size waistband hold the underwear in place very well when changing cloths.
I love the cut of the back! I love the tighter fit that I got because it is even more cheeky than if I went one size up. Though from the pictures, I do really like the look of the little cheeky-ness you get as well. Very playful and sexy. Same goes for this print with the ice cream. Supawear has won me over. Nice one! I want to try one of the thongs next!
