Viva La Bolero!
A bolero jacket, inspired by the matador’s chaquetilla, is essentially a short fitted jacket meeting at one point in the front with a closure consisting of a hook-and-eye, button, or tie.
This is a motif pattern called “Elegance for Evening” available online free at:
I used size 20 thread with a No. 10 steel hook to fit a child size 3. It would look lovely with decorative yarn and lace trim. I added a crochet collar and made the closure a hook-and-eye clasp, but a fancy button would look nice.
