Many years ago, somebody or other — some annoying self-appointed style guru — came up with the concept of age-appropriate dressing. The basic idea is as follows: The older you get, the more conservatively you should dress. Color and flamboyance are for young people. Restraint, propriety and formality are for elders. For some reason it was decided that once women hit 50, they should ditch that metallic snakeskin disco purse and start dressing like depressed librarians, circa 1940. Yawn!
