What’s being featured here—the woman or the frig?
It must be hot, because she has on a short sleeved shirt and shorts. That’s showing a lot of skin for an older woman, at least according to fashion advisors.
The clothes here are hard to date. Shorts were a popular summer item since the 1920s. Her button up sleeveless striped top is also a classic. The combination could be a 1950s separates set. Thr cat eye glasses were in style in the fifties and sixties, but many older women wore them longer because the shape gives the eyes a little lift.
Maybe the huge refrigerator can help. Side by side models existed since the forties, but they became very popular in the seventies. The extremely square shape was also typical for the decade. So I’m guessing early to mid-seventies here. This one look big enough for her to climb into the freezer side.
My own summer style is more covered up, with loose cotton pants combined with a loose cotton tops, at least elbow length. Shorts are not part of my wardrobe. How about you?
