Jacket by Atea Oceanie. Cult designer brand from 2010s.
This is a sample that was used once in a photo shoot and has been in storage since. It has no interior labels - but if you're familiar with the brand, you will be able to tell it is Atea Oceanie - you'll certainly recognise the quality.
There is some minor creasing/marks to one sleeve (see last photo) but otherwise it is like new.
Single breasted, fastens with single button. Inward collar, can be folded back. Welt pockets. Long sleeves. Lined.
See photos for detail and email if you have any queries.
UK 8, please check the measurements. Approx measurements in inches when laid flat: underarm to underarm 18, length from shoulder 25.
