J. Crew Embellished Garcon Shirt in Stewart Tartan Cotton Poplin Plaid Long Sleeves. I bought this shirt in a zero and size 2 not knowing which would fit, the shirt runs a classic looser fit, so the zero was fine, I never opened the size 2, but I cannot return it. Originally $128.00. A dressed-up take on our garcon shirt.... This version of our just right shirt fit sits somewhere between our slim and oversized styles. Plus, it comes with jewel buttons at the collar and cuffs for some added sparkle and a classic tartan print. C . 100% cotton . Long sleeves . Jewel buttons at collar points, collar band and cuffs .
