Nano Fit. Sits low, really low. The waistband has been expanded and is a little wider than it used to be. Not too horribly wide though as to spoil the overall feel of the briefs. I actually quite like the new, wider waistband as it gives the appearance of the briefs not sitting too low on the waist. I loved the bright pop of purple that these were when I saw them online, but seeing them live, it was a whole new case of purple, one that I enjoyed even more. It’s a great pop of colour and it has some amazing contrast with the silver of the waistband and the green contrast stitching. Am in love with these briefs. Not too skimpy, not too full!
