What is too old anyway? Society hasn't said what age you become specifically too old for anything, I am a 26 yer old mother of 4. I still have all the toys I played with as a child, not just for my children but because I still like them.
I have unusual style, and if I want to dress like I'm 12, I will. I get funny looks and pointing as I live in a small town in South East England, and other parents look down on me due to my fashion sense, but I don't care.
My family have always had to accept my clothes choices, my children love it as they don't know me any other way, and my freinds wouldn't want me any other way. I am not prepared to grow up or dress conventionally to blend in and become more socially acceptable to people who have no idea what style is; conforming is boring, being yourself and having your own style is far more interesting, if other people cannot accept you in the clothes you like, it is their loss.
