After watching The Royal Tenenbaums for the first time, I noticed something...
Chas Tenenbaum and Sue Sylvester are soulmates... well, at least their tracksuits are. And do formal occasions get in the way of their tracksuit wearing? OF COURSE NOT.
Here's Chas, modeling the funereal black tracksuit:
And Sue, donning the tracksuit wedding dress-- perfect for marrying yourself!
To sum up...
Awesome people wear tracksuits. All. the. time.
