Very Studio 54. And I love the batwing sleeves.
It's a small but runs large to size - is a good fit for a UK10 (oversized) - UK12 (loose).
43% silk/ 41% viscose/ 16% wool.
In good condition. There are a couple of fabric pulls (see 2nd photo) but these are not noticeable when on. I have, however, marked down the price to reflect this.
