M&S nightie Rosie for Autograph floral & lace nightie

Reposhing this item I purchased from @sunnydaez. Loved it, but it was a fit too big for me, so I am returning it to the world. In excellent vintage condition. There are no care or size tags, but I think this is probably polyester with some spandex or elastane. The fabric is silky-soft and has some stretch. It has an A-line shape and measures approximately 18.5 inches across the bust, so it would probably best fit a large or extra-large.
