I'm a huge red fan. It's bold, bright and classic. And that little Sargent Pepper outfit ticks all the boxes for me - bold, classic, and tailored. I'm a huge Beatles fan - even though I am far too young to fully appreciate their musical genius in context of the times they rolled, I know a good tune when I hear one.
If your are more suited to whimsical, Enya style ballads, then the sheer chiffon number is just perfect to flutter around like a nymph in an enchanted forest singing 'paint the sky with stars'.
