I'm not sure about selling one for the other but I can point out pros and cons of the Chanel (that stand out to me) that may help you make a decision.Logo is big yes. Same with my chanel 22.
sell the chanel for the ysl?
awesome! The ysl is just so unique and cool I feel like. I normally am not a ysl girl but this bag did me in..but I also like big logos! I just see getting so much use out of both! Congrats on both btw
