Most guys have no idea what it means when something "fits." They just know if something feels "too tight"—which generally means fabric is tugging at their body in some way, shape, or form. That's why many guys end up wearing a size or two too big—especially when it comes to tailored clothing. It's all about finding a blanace between what feels good and what looks good on you, and for a seasoned menswear pro, it comes down to tiny fractions of an inch to get there.
