Jacket transformed into a vest by Michelle Paganini. Rip out the sleeves and remove the padding. Lower the armhole. Widen the armhole especially in the back. Take in the princess seams and shoulder seam to get the armhole to lay against the body. Turn under the armhole seam, hand baste then finish off with bias tape.
