I emailed some questions about the suit/sizing before I purchased and of course the customer service was spectacular as always! I was hesitant because a suit is a serious investment and the guy I spoke to offered me a 15%discount in order to take the plunge. Needless to say I was stoked! I'm 5'10 180 lbs muscular build, and I ordered the 38R and it fits like a glove. I would highly recommend this suit, it looks sharp, fits great, and Bonobos is the best around. Couldn't be happier. Keep up the excellent work!
