hmm, if it wasn't for the fact that you already have a red bag, i would say go for the red. but becuase you already do, i'd say the white. it really is quite pretty, but overall, regardless in caviar or lambskin or perfo, white will be slightly higher maintenance. i wll be venturing into my first white bag shortly, i have a e/w white cviar in the new chain on hold for me. white is great for the summer, and i think is an essential piece for one's collection. So, make your decision and go for it, but if yu're hestitating, then you're better off holding off until you're sure.
i originally wanted to get the new bijoux chain, but Sydney boutique only have lambskin on all colours and there is no bright colours beside white, come to think abt it, i shouldnt have bought it and hold on to next upcoming colours ... hahahaha, i blame this all for Sydney Chanel stock, not helping at all ... i will consider what u and others said in less than 24 hrs before i make up my mind and take a photos of what im gonna keep or exchange ...

btw, lucky u to get the caviar white, the new chain is stunning, its a must!
