Talking about underwear, right size does matter a lot. Not too fit, not too loose. The perfect fit is what you choose.Underwear should streamline your physique. It is advisable to follow the size recommendations, but your body type makes an even bigger difference. Comfort is at highest when your underpants fit you perfectly. If you wear a little bigger or a little smaller pants due to your gut feeling, the undies don’t function as they are supposed to, and during use you will encounter unwanted characteristics (for instance rolling, sliding down, riding up in to your A**).
