The three major don'ts: Tight collar, lose cuffs and relaxed fit that is too relaxed of a fit.
Collar: The correct circumference measurement should fit one finger in between the band and the neck, no more than that, no less.
Cuff: The length of the sleeve (for long sleeve) should be at the top of the thumb bone that is below the wrist, where the hand starts. A good cuff should feel not too lose that it dwarfs the hand or too tight where it does not allow enough room for the watch to slide under (It would be all right to have two different measurements for both wrists).
Fit: Depending on your body type, different cuts fit different men. However, the relaxed fit of the ready-to-wear shirt that fits an athletic man because it fits his large neck, tends to add weight that he may not necessarily have on his body. Please consider having it tailored so it does not add bulk and it lays nicely and flat without extra gathering and volume.
