This white Haider Ackermann oversized mandarin collar shirt is made with a cotton mix blend. Featuring long sleeves with buttoned cuffs, this shirt has a front button fastening, chest patch pocket and straight hem. If you like to keep some extra shirts in your desk drawer, à la Don Draper, make sure they are Haider Ackermann, as our favourite suave ad man once said, 'Success comes from standing out, not fitting in.'
