I had two very different grandmothers.
I remember my one grandmother wearing her apron. Hers was the full kind that covered the chest as well. I don't remember her ever without hers on. She was Italian and therefore ALWAYS COOKING AND FEEDING! Another thing that I remember is that she always had shoes on and always wore a dress.
My other grandmother was always in the kitchen in flip flops, tank top and shorts. I believe the difference is one was from NY and the other from CA! The age was just about the same.
I think I'm going to start to wear an apron (even though I'm not a grandma!)
