Our Fil-? -Fil Spread Collar Fitted Shirt, in 100% cotton, features a slim fit, spread collar, a single chest pocket, an allover subtle pattern and a signature box pleat with locker loop at the back. (Design side note: Fil-? -fil, which from French translates to “thread-to-thread”, is a type of weave created by alternating light and dark warp and weft threads, resulting in a heather effect.)
