Size Guide
To find your ideal size, get a tape measure.
How to take your measurements:
(1) Collar size: Lay the collar perfectly flat. Measure from the center of the button to the edge of the buttonhole, not including the end of the buttonhole.
(2) Shoulder width: Buttoned shirt, laid flat. Measure the distance between the two shoulder-armhole junctions.
(3) Chest width: Buttoned shirt, laid flat, front facing up. Measure from one armhole point to the other.
(4) Waist width: Buttoned shirt, laid flat. Measure 48 cm below the shoulder, from one side to the other.
(5) Sleeve length: Shirt laid flat, sleeve in its natural position. Measure from the shoulder-armhole junction to the end of the cuff.
(6) Back length: Buttoned shirt, laid flat, back facing up. Measure from the middle of the collar stand base to the bottom of the garment.
