DD is 13 and everything in her room is shocking pink.
She also has pink tops, socks, converse boots, pens, school bag etc etc ad infinitum.
It is also bizzarely combined with the normal teenage emo ethic, so combined with ripped up old jeans and hats, and pink streaks in the hair (not my doing, done by dd and my stepson on the sly )
So, in to your question it never ends!
