We gave our classic Mill shirt a special wash to make it feel even softer and lived-in. - Classic button-down collar and relaxed fit that you can wear tucked in or not. - Real shell buttons and finished with our signature "X" stitch detail. - We love wearing this one year-round or layering it under a sweater when it's chilly. - Fits true to size. - Size medium measures 19.5" across the shoulder, 45.75" around the chest, and 30" long. Sleeve length measures 35.5" from the neck. - Idris is 6'1" and wearing a size medium. - 100% cotton.
