Re the waistcoat, they sent me this. Nervous to buy a 10 though might go for the 12 anyway.
Please see sizes below:
Cotton Linen Canvas Waistcoat Top | Wood Ash M
Bust: 49.9cm flat
Length: 55.5cm
Cotton Linen Canvas Waistcoat Top 10
Bust: 50cm flat
Length: 55.5cm
Size 10 in the Cotton Linen Canvas Waistcoat Top should be the same as the Cotton Linen Canvas Waistcoat Top | Wood Ash size M.
