From Merchant & Mills:
This is a PDF pattern that will give you the relevant pattern pieces to make a button back Trapeze dress with sleeves, short sleeves or sleeveless.
NOTE: Please note you have to already have the Trapeze Dress pattern [the pullover version without buttons] in order to make this, these are just the additional pattern pieces with instructions for those parts. If you already have the updated Trapeze Dress pattern with the buttons, you do NOT need this addition.
