actually this dress have stitches ( I have done for fitting) so size can be varried by opening these stiches

size XL - bust - 38 inch /waist 34 inch
size L - bust - 36 inch / waist 32 inch
size M - bust - 34 inch / waist 30 inch

I am wearing M size so you can opt as it is.
if anyone want L or XL they can easily open stiches nd can wear
