Crosby is the same fabric as the metros and suttons? I’ve not seen anyone observe color fading in this forum (I’m not on Facebook). I haven’t had any fading in any of my metros, suttons, or any of the crosbys (just micro, crossbody, and small crossbody). Nor do colors ever rub off onto other fabrics thank goodness, one of the best things. I’ve washed in the machine a number of these bags, a vibrant papaya sutton has had multiple washes. They come out sparkling new, maybe a little softer and of course the leather has been wet.
Maybe if you try a wash the fabric will brighten back up!
One thing about the Crosby crossbody is its leather corners get really worn which looks terrible.
