Vintage Bergdorf Goodman ABS Leopard Flower Vest

OMG how cute is this! Purchased at Bergdorf Goodman and made by ABS California. I'm guessing this is 80's era but I'm not sure! Size marked is P. I'm guessing it's a S but it only says Petite on tag; please see measurements. Measurements: - Overall length (from top of shoulder to front point): 24" - Pit to pit: 16" Excellent pre-loved condition but please note could use an ironing as well as buttons are a bit loose and would benefit from a few stitches for reinforcement.
