Around 14 but it also depends on hip size.
Women's size 14 is a 36" waist
size 14 waist to jacket size
38-bust 32-waist 40-hips
waist size is on how many centimeters your waist is around like size zero is really small and over size 14 is big.
In the UK a size 10 dress or skirt has a 28 inch waist and sizes go up in increments of 2". Size 12 would therefore have a 30" waist, size 14, a 32" inch waist, size 16, a 34" waist, size 18, a 36" waist and so on. For a waist 33" you would either have to settle for a size 14, with a 32 inch waist, or go one larger and get a size 16, which would have a 34" waist.
I am a UK 14 and my waist is 29". I don't know if that helps!
