I imagine the Diamonds are the best candidates are Diamonds. Avery, will you be Challenging Sade in fashion. :|a

Also I like the idea of someone Challenging Cadogan in something related to fashion and feeling very smug because he's neat but utilitarian and then suddenly
a distant rumble
which gets closer
and suddENLY
A FLAMBOYANCE OF ADRIEN.

And then Cadogan wins because best coach ever.
