1990's Anne Fontaine Black Jersey Sleeveless Ruffle Top.
She's great on her own but designed to work seamlessly with a jacket. Made of a thin, soft, stretchy synthetic fabric, the contrasting stiff ruffles are just adorable and there is a nice double front zipper so she's an easy fit. Appears unworn.
Collar 11", bust 32", waist 28", hips 32", length 22".
Modern size is XS/S and condition is Mint.
