I appreciate that clothes sizes vary a lot. I take careful measurements of all items I sell. If you are unsure on sizing, please check these carefully, and even compare them with a similar item that you already own and fits well
Sizing details below are of this item, fully fastened (where possible), and laid flat:
Armpit to armpit - 18.5" / 47cm
Waist - 15.5" / 39cm
Total length to front hem - 44.5" / 113cm
Total length to back hem - 50.5" / 128cm
