For day to day wear, the classic “mature elegant look”, eg the “clever secretary” , Lois Lane look of the 50’s and 60’s. Black skirt and jacket white blouse, black low heels and tights.
Followed by “neat casual going to the mall” no particular model, but my Mum was a great example.
As for other females influence, my love of long formal wear arose from seeing one of my ex’s friend’s dropping of her kids at our house before going off to a formal Ball. Immaculate hair and make up and wearing a long apricot chiffon gown. Gotta be 40 years ago, but I can still see this “visage” in my mind to this day
Her name….?? Of course it was Catherine..
