Is it me, or are black and grey shirts out of fashion this year?

I've been everywhere and I cannot find a single black or grey shirt. The one or two I do find buried under piles of *gasp* colourful shirts are either several sizes to big or have been trampled on...

I seem to remember just one or two years ago, there were entire stores with half their shirts in black or grey. Maybe I'm imagining things? What's going on with the lack of black and grey shirts?

This isn't good, since I've only got a few grey shirts to live on at the moment!
