This roomy pullover style is traditional garb for cheesemakers in Roquefort, France, and a comfortable smock for your studio or daily outings. Popular choice for Medieval and Renaissance reenactors, as well as for making an everyday tunic-style shirt. Sized for men and women, the easy-sew smock features shoulder yoke, front placket, simple narrow buttoned neckband, and optional underarm gussets. Sleeves are gathered at the wrist into a buttoned band cuff.
