ADIDAS - Label size girls 13-14 years - I'd say will suit a ladies UK 4-6 (or slim fit UK 8). @ 17.5" pit to pit.  24" length. 28.5" neck to cuff (no shoulder seam).  Very good used condition (a couple of pulls, leave tiny lines - see last photos - but you have to squint hard to spot them!) I'm told it is 'Rita Ora' but I can't see any labels confirming this. There are Adidas labels. It was a gift that my daughter has outgrown. Gorgeous colours.
