Fashion. You seem to get the same sort of amount of people with 'eclectic' fashion sense in London as you do in Brighton (esp. on my route, via Camden), but you also get the almost unfeasibly co-ordinated.
For example, the woman across from me on the tube, black trousers, black shoes with red trim that compliments the red tank top type affair over the red-striped white shirt, and the chunky bracelet and necklace that almost perfectly match her bleach blonde hair.
You just don't see that sort of effort in Brighton.
