Eventho I love the coco cuba, i'm not a fan of the fabric in the woc given that it has to lay against your body/therefore jeans... i would worry too much about it and the entire point of the woc is to be "carefree"... i would say sell and get the small gabrielle that is the new IT bag i'm so in love with the different color hw and just how it's structured and slouchy at the same time plus in color black you won't have to worry about color transfer.... good luck with you decision love
You are right, i m going to sell my woc and think for a while about the gabrielle bag because i dun want another regret moment.. for me it is so much work to do to sell a bag, i kinda lazy to posting it or send it to a reseller..It sounds like you have already made up your mind. If you "kind of dislike it now," that will just turn into "don't like this at all" as the months pass and you hang on to it instead of getting the bag you think you know you really want. In short, no you won't regret selling it.
Side note: if you didn't like the Gabrielle at first and thought it was ugly, maybe sell the WOC and think on it for awhile. You don't want another bag you liked for a moment ultimately to decide it isn't really for you. Those mistakes can get costly fast.
