eek eek eek!

I have just scrambled the forums looking for the right place to put this and saw " when things begin to pear shaped" so i think here suits!

I recently bought this really nice shoulder bag, cost me a few bob to say the least but its kinda of white/cream colour. Anyway i was keeping it for college cause its just the right size but it was in the wardrobe on top of a piece of colourdy paper (an advert or something). so i pull it down from the wardrobe and the colourdy paper has transferred on to the white bag. It looks filthy and awful, i tried rubbing it off but no luck. Anybody have any suggestions?

The bag isn't leathery but feels that way, its lacoste and all their bags feel the same i think, so you might know?!

Please help!

Thank you sooo much!

P.s. i blame my bf entirely for the piece of paper in the wardrobe!! haha!
