Which to sell?

i'd sell the celine first b/c i think it's a trendy bag that won't withstand the test of time. however, if you love it then definitely keep it! between the cerf and gst, i'd sell the cerf.
 
The Cerf. It's a great bag but the color makes it harder to care for compare to the other two. Despite the GST and Celine both being red, I feel they're very different bags and both will be more timeless than a light color Cerf Tote. Also in all honesty, Cerf's resale value isn't great so I would sell it sooner than later (when it will be worth even less).
