In my experience Natty's customer service was great but their quality control was lousy. Ordered a regular fit. They describe it as 5" margin added to chest, waist and seat body measurements. Unfused collar and cuffs and no gauntlet button. The shirt had a 2" margin and was unwearable. I couldn't even put it on as it was pullover style. Collar and cuffs came fused and there were gauntlet buttons. The replacement shirt was wearable, though not a good fit. Collar and cuffs were fused again and the unwanted gauntlet buttons were present as well. I am certainly not a returning customer.
