I think Pearl wants to drop down two sizes i.e. from size 18 to size 14 . I think I incorrectly assumed it was one dress size so there is quite a reduction if it is todays sizing and is not a vintage skirt?
size 14 31 80 41 103.5
size 16 33 85 43 108.5
size 18 36 92.5 46 116
So that by my reckoning is 5 inches (two and a half inches each side?).
