XS
If this fit me, I'd be keeping because it's the perfect throw-on shirt/jacket. It's super soft and has a lovely vintage vibe to it, with military-style details throughout. It's lovely and cropped so would look amazing layered over a tee or a dress. Also perfect for festivals/gigs/pubs as you can tie it around your waist. Push stud fastening.
