When I used to be a kid, my mum was keeping her suits, dresses she had from her teenage years some of whom she would have photos with. From childhood I liked her style, she always has / had that fashion taste ahead of me, through which she would buy elegant clothes for her daughters and sisters as well.
Wearing from mum's wardrobe is a brilliant choice, you are lucky if you are the same size, something which me and my mum left long years ago and it was only her teeenage years clothes that would fit.
