I really want to buy a YSL downtown muse. but i don't know what colour to buy. red or white?

If it were me, I would go with white. While I love the red, I think you will get more use out of the white. I have a really expensive Tod's red bag, that I love, but I just never use it... on the other hand, I have a brown Prada bag (not white, but, a neutral none the less) and I get a lot of use out of it.. If you're going to spend $1900 on a bag, make sure it's one you'll get full use out of :) Great taste by the way - I love that bag! I just bought the YSL Y-Mail clutch!
