“As a tall guy with broad shoulders, every shirt I buy off the rack is too short and wide. I’ve ordered roughly 6-7 shirts from these guys now and cannot speak highly enough of their products. Great quality, good tailoring, great customer service. I will never buy another shirt off the rack again.”
Reid in San Jose
“I have a weird body: thick neck, short arms, big chest and shoulders, and bit more of a tummy than I would care to admit. I decided to give Proper Cloth a very skeptical chance. And I am very glad I did... Perfect fit. I cannot recommend what Proper Cloth is doing for us oddball shaped men more. Thank you so much.”
Tyler in Chicago
“I am 5′ 5.5″. Stocky build. My 18 and-a-half inch neck has been genetically engineered to support my massive melon of what passes for a human head. Yes, I have a belly, and I have broad shoulders and a wide back. Somewhere between a Tolkien Hobbit and Dwarf. My new Proper Cloth shirt isn't just a shirt. It's the start of a new wardrobe that makes me look and feel as close to great as is possible. Seriously, Proper Cloth is THAT good. Bravo and thank you.”
Bill in Los Angeles
