Hi, i'm thinking of getting the NINA, i've been staring at this bag for sooo long, usually my money goes to jeans..but recently, ahh i want this nina in slate sooo badly!! can anyone who has the nina provide any info? how does it wear? does it change colours? i've read in the forum that they found it turned yellow! as well, how does the chain feel against clothing? i'm always worried it will snag my clothes but it's soo chic looking.. tia!
