H&M x Lanvin Purple One Shouldered Dress

This dress is from the H&M x Lanvin collection designed by (the late great) Alber Elbaz. It is a size 34 / UK8 (but note that this dress would best fit a small 8 as it sizes small).

The dress has a sculptural one shouldered design and a black waistband. Side zip closure. Dark purple (similar to an aubergine) colour.
