The shape of this dress has quite a significant nod to the 60s. Beautifully tailored.
The size label is a FR40 (a UK12) but it definitely runs small to size and is better suited to UK10s. If you have broad shoulders I'd say this is likely to be a little tight across your back.
A viscose/ silk/ polyester mix.
Sits mid thigh in length.
In good condition.
