What period is this dress styled after?

It has hints of classic Hollywood, but the rouching is now. I believe the sleeveless is also a new trend. Very nice.

it’s a late 1940’s glamour gown. love it

I would say 1930s/1940s. Do a Google image search for 1930s or 1940s evening gowns.

Similar 1930s dress

Gorgeous gown. Very much like the 1940’s and 1950’s glamour gowns. A search on 1930’s fashion turned up this information about bias-cut evening wear. So the concept of the sweeping form-fitting gown really took hold in the late 1920’s, early 30’s, and took a hiatus during the lean years, and really surged back in the late 40’s and early 50’s when everyone was recovering from the privations of war.

It’s 1930’s and classic gorgeous! It will never go out of style. I’m having fun imagining the possible colors. They didn’t have the dye possibilities in the 30’s that they have now.

I’m getting 30s-40s too. Love it.
