This dress is super cute... when I was trying it on for size even my husband popped his head up and commented how great it looks (unheard of)!
A medium - a good fit for a UK10. Despite not being boned, it has amazing 'staying' power. I would say it could happily accommodate up to a D cup (although probably best suited to B/Cs.
Sits about an inch above the knee (based on a height of 5'7")
100% cotton. Fully lined.
In excellent condition.
