I recently made a fairly simple asymmetrical dress that can be worn multiple ways.
Please excuse the low budget drawing I've added to quickly explain the dress pattern. These are the particular measurements of the dress.
A) Is the head opening.
B) Is the shoulder seam. In my dress I added two drawstrings ( 40cm in length each) so that the shoulder seam can be cinched.
C) Is the armhole.
I made this dress out of a bargain bin fabric from Fabricville and some Dollarstore ribbon.
The end result is one dress that can be worn in multiple ways.
