Jackets / shirts:
Button up your clothes and place them on a flat surface. Measure from the left to the right edge just below the sleeves.
Wear a shirt you like and with one arm by your side measure from the shoulder seam along the arm until you find the length you want. We recommend that the cuff runs to the base of the thumb (at the wrist).
Button the pants and place them on a flat surface. Measure from the left edge to the right edge at the waist.
Button the pants and lay them out on a flat surface with hems on both edges. Measure the distance from the top of the waistband to the end of the leg.
