Fashion: Don't fade to grey - the 2013 look is black and white all over

You can't open a glossy magazine or go near a high-street store without realising that the spring/summer 2013 look is black and white all over. Monochrome was everywhere on the catwalks (see Marc Jacobs' take, pictured), and now Zara, H&M and co are packed to the rafters with the stuff.

All very well, but how the hell do you wash such contrary garments? Surely the white will go grey as soon as it gets in sight of a washing machine (the reason I never buy garments that are black and white at the same time)? The Independent's fashion desk rides to the rescue, suggesting either: 1) Use a colour-catching laundry sheet (either Bounce or Shout). 2) Try starch tablets to keep whites pearly. 3) Don't dry clean: it can make stark patterns murky. Or do as I'm going to, and stick to separates or shoes. That way there are no grey areas....
