I knwo exactly what you mean: that moment when you look in the mirror and see silly and frilly rather than wild and glorious. You'll find a hint of "controlled flamboyance" at Jasper Conran (great at Debenhams). Go for discreet gestures - necklaces, shoes, cuffs - rather than grand statements. I wouldn't fully dispense with your dottiness though - I'd much rather chat to an eccentric than a drone.
