Today’s Friday, and while for most of us that means the beginning of the weekend, it’s a particularly special day for one charity.

As part of its latest campaign, Fashion Targets Breast Cancer has declared today Fashion Friday, and it wants you to get involved in the fun.

So here’s what you do: take to Twitter and tweet what fashion means to you using the hashtag #FashionIs, or share your fashion memories with friends on Facebook – the idea is to get people talking about the great, the good and the gorgeous of this industry to raise awareness for the pioneering charity.
