This photograph was taken in the late 1920's and represents how a typical woman would have worn her hair and clothes.
She was all the rage with a wavy bob that has a side part and is cut to ear length. The ends flair out a bit giving this 'do a less manicured look. Her glasses are round and on the large size. Her expression looks a bit mischievous which might tell us a little bit about Minnie's personality. We know her name as it is handwritten on the photo. Here is a close up of her.
Her dress has a low waist and is loose fitting which was fashionable. It is knee length and has tiers around the skirt.
