Found this amazing dress! Its really hard to get photos of but has a metal zipper on side and amazing detail. Trying to properly date and describe style
That is a beauty Emily! I don't know if there's a name for that sleeve (paging Hollis @pastperfect2 ) but the look is 1946-ish to my eye, with the way the sleeve emphasizes the shoulder. Are their shoulder pads?
Agree with Maggie: I would put this one just post-war, with some remnant '30s design features. Lovely dress, the sleeve treatment is wonderful. I've had dresses with sleeves like these but also do not know of a specific name for them, sorry.
