Gorgeous and unique Zimmerman blouse - with tag

Gorgeous blouse with impeccable quality - typical of powerhouse Zimmerman. It’s lovely, unique and super light. Size 1 Australian. It would fit US size 2-4. I’m a 0 and it’s too large for me sadly. I purchased it for myself but it’s too big. Two plastic tags and one paper tag still attached. The Zimmerman tag has been misplaced unfortunately. The blouse is like new with no defects or stains. Never worn.
