Dirty collars, blue by convention

I change at school, just to save wear on my business shirts. Usually I’m dripping in sweat when I come in. Looking at my shirt in the morning, I just realised what sort of collar grime I’m going to have to contend with come Friday. When purchasing a shirt it’s one of the requisites that it has to be a dark colour, which this is not. Still, convention states that there are only two colours, and only two patterns. White or blue, plain or striped. Who the heck thinks up these conventions?

I still bought the shirt though, they were on sale.
