Do women typically wear one style of clothing today such as the housewives of the 40s, 50s, 60s,& early 70s?

My grandma who is 76yrs old and a housewife wears the same clothes she did when she was in the 60�s and 70�s. The same clothes she wears while inside the house like the aprons, robes, house coats, ect is the same clothes she wore back then. But when she goes out she wears different things like granny jeans.
