Well you're a posh lass obviously harrigran, very refined 
Iam64 I too was brought up to avoid appearing common at all costs, as well as applying the word to women and girls (never men, for some reason), items of clothing of which my mother disapproved, such as patent leather ankle strap shoes and velvet party dresses were also dismissed as common.

Needless to say I now possess a lovely red velvet dress and at least 3pairs of patent leather shoes 
A to Z of Tv shows/movies titles backwards
This made me quite teary - but smile too
