I came across this picture from the last. ever. Rakehell's Revels. Unsurprisingly it reminded me of a trend I actually spotted (as in, I saw it in real life and not on the internet) which was named 'double dressing' by The Future Laboratory.

If you hadn't guessed, double dressing is when people wear matching outfits. The first girls I saw doing this were some south London rude girls dressed identically from head-to-toe. Same hairstyle, same hairclip, same pink MacKenzie jumper, you get the picture. I was in my pyjamas looking for a Guardian on the Walworth Road and had neither phone or camera, but these girls made a massive impression on me.
It got me thinking about how powerful the visual impact of dressing alike is in an age of individuality. Think about Gilbert and George or Viktor and Rolf - their outfits centre around quite plain suits, but the act of doubling it up make it a much bolder visual impact. I think formation dancing fits into the same social category.
