From FibreMood:
Dreamy and romantic, that's the way Rosa’s winds are blowing. It’s got every detail a pretty-in-pink girl needs to tickle her fancy, from the convenient patch pockets and simple row of buttons to the way it billows and swirls when spinning around. Look for the delicate ruffles at the waist and the top and bottom of the sleeves, just above the delicate cuff. Not crazy about the cuff? Then leave it off. That way you’ll be left with wide three-quarter length sleeves.
Fabric advice
Knit fabrics make it difficult to sew some of Rosa's details. For the perfect puff effect, we recommend a more structured woven fabric. Poplin, eyelet lace, etc. will look like a dream!
