This is a flirty late 50's early 60's dress with a lovely draped high neckline and a full skirt.
The blue chiffon has a floral pattern with amazing touches of white and lavender.
There's no size tag, but I'd call it an XS with a chest 30" and waist 24."
I wish I could fit into this lovely dress, but I just don't see that happening and I can't bear for it to languish in a drawer.
I'm happy to answer questions or provide additional images.
Thank you!
