Cute! I can see why you would like the pattern.It has great possibilities from cottons to taffeta and even chambray for a sporty look. To adapt another simple pattern would be very easy.
This pattern appears to have the bodice ruffle set into a seam. You could simply add it on top and continue it over the shoulder. That way both ruffle ends would be sewn into the waistline seam and it would give the back a bit more interest. If necessary, you could "borrow" a sleeve from another pattern, shorten or lengthen it.add a ruffle and you
are home free. I would suggest that you borrow the sleeve
from the same size and brand of pattern you are using to
get the best fit when sewing it into the armhole. Good luck!
