SIZE: 42/XL on tags. I think it would be wearable from a 10 through to a 12. For reference, I'm 174cm tall and a smaller busted 12 on top and a 14 on bottom and it was feeling snug on me.
MEASUREMENTS: Chest 57cm, Waistband 40cm and Length 128cm
The most similar style I could find RRP $850-1000 at workshop here in NZ
