Approximate measurements
Pit to pit 10-3/4”
Length center back 20-3/4”
It does stretch
Very soft, my granddaughters did sleep in it.
I think it is supposed to be a nightgown, but would work for a costume dress.
Has some scuffs ? (not really sure what you call them) in the outer sheer lightweight fabric from laundering. (See photos)
Please see photos for actual condition and description
Thanks for looking!
