This is beautiful - fantastic pleats and lace detail.
It is a medium but I'd say it runs a little small and is better suited to a UK8. It sits just above the belly button... so not hugely cropped. Would look incredible with high waisted jeans/ trousers. If you don't like showing even a centimetre of midriff then this would look equally amazing layered over a crisp white shirt.
The fabric label has been cut out but I'd say it's polyester.
In excellent condition.
