Late-1940s/early-1950s. The setting for this shoot may have been Irene’s boutique at Bullocks Wilshire. A paper label on the back of the photo reads:
5170 Check silk day dress with black taffeta trim $95.
Also annotated in pencil “Irene Collection.”
This and its companion photos were probably taken for distribution to the department stores licensed to sell Irene’s collections. They don’t look like editorial or advertising shots. Perhaps they were included in some kind of catalogue?
