The Genes or the Jeans?

I am a menopausal 57-year old and my daughter is a stunning single 30 year old. We love to do lunch, shop and shmirshky talk. More often than not, we find ourselves showing up for lunch in the same outfit. My mother, who is now 90, always dresses fabulous, but we have never ever dressed similar. So is your fashion taste a function of your genes or your jeans?
