I used the Oliver + S Roller skate dress, modified, of course. Also, in a size 4 and a size 12m. I constructed it slightly different as I didn't want the raw edges shown on the black layer (aka lining layer).
I used the pirate as the "main" layer, black as the "lining" and attached the striped fabric to the black.
I think they turned out pretty well, and similar to the inspiration dress, my friend seemed to like them too. Can't wait to see pictures from her vacay and live vicariously through her, haha!
