Help dating Blush Pink Silk Rayon (?) Nightgown (?) Dressing Gown (?)

[LaurenMG]

Hi Everyone,
I'm kinda lost on this. 50? Would this be considered a nightgown? A dressing gown? No labels, the inside seams are pinked. Thanks for any help. Lauren

More likely a nightgown than a dressing gown since it goes on over your head, mussing up hairdo and makeup.
