An important rite of passage for any mid-century girl was to wear a dress that matched mom’s. In our family, this event was generally on Easter. My mother would sew matching dresses for her, myself, and my sister. This was a yearly ritual that was fun for all. It was a treat for us to wear, and a treat for on-lookers observing a matching set of related females.
The charming picture of a mother and daughter wearing matching sundresses that you see was part of a fashion article in the June 1954 edition of Good Housekeeping magazine called Cool Cottons for You and Yours.
Mother and daughter wear pretty princess-style sundresses with ruffled camisole tops and full, gored skirts.
Here’s another mother-daughter sundress from the same article.
These dresses have fitted bodices with solid color piping and shoulder ties. Mother’s about $8. Daughter’s about $4.
