Cos off the shoulder black bandeau top

This is a really beautiful off the shoulder top from Cos.

Its listed as a slim fit and I’d say it runs quite small as it’s a size 42 which is converted as a size 16 on the Cos website, but I’d say I’m a 14

Description from website

Crafted from 100% recycled voile in black, this modern blouse is designed with a voluminous panel that contrasts the more fitted bodice. The central seams keep it structured, while the side slits make it easy to layer over shorts or trousers. Style it with a chain necklace to draw the eye towards the off-the-shoulder neckline.
