Mono-colour...

I'm just curious... at what age does one decide dressing entirely in one colour is a good idea?
I know it can be a good idea, but it's not a good idea in this instance.
Even the shoes are maroon... surely that is a bit overboard?
I just can't help but wonder if her entire wardrobe is full of hangers that have jackets and trousers in identical colours (green, navy, maroon, lavender, yellow...) with matching loafers underneath? If so that surely would be a sight to see. If there were a matching underwear drawer it would be even better!
