70s Ship n Shore White Sheer Long Sleeve Blouse - I thought this looked good with zipper in back, but also with zipper on front!
No material contents tag, feels relatively soft. Approx 38" bust. 35" waist. 14" shoulders. 20. 5" long. 22" sleeve. Model is 5'1" XS and blouse fit loosely as shown. Would be best on size S I think, you'd not want to wear it fitted and the length is short plus shoulders are narrow.
Nice condition - no flaws.

This item is sold from an excellent, highly rated vintage boutique.
