From Lydia Naomi:
This cottage core, princessy, romantic blouse or dress features a bustier like top with gathered ruffle cups, a ruffled puffed sleeve and a ruffled hem for the blouse, or a half circle skirt with a slit for the dress. You can add boning and fully line it or construct it without these features. View my two different tutorials for construction options.
This pattern does not contain written instructions but rather has a very comprehensive video tutorial on youtube.
