Bodice and sleeve: Aldrich flat shirt block.
Collar: Aldrich 'shaped shirt collar with stand'
Sleeve shirt cuff instruction: loosely base on Myoungok two pleats shirt cuff.

Issue: As usual, one-piece sleeve creates excessive fold at front upper arm. Next time will try with smaller armhole, probably with more dropped shoulder.
