This is the "Kaisa" jersey blouse from Ottobre 1-2009-12. The neck and bodice are gathered with clear elastic tape and the sleeves are slightly cropped. Sara's grown a little since I traced this pattern in May, so I added 2 inches to the length and a little to the sleeves. Plus, I expect this Hobby Lobby knit to shrink even though I prewashed and dried it twice.
The heart pocket pants, which she wears continuously, are featured here.
