Hi, I'm considering purchasing a pink iridescent medium flap, however I'm wondering how the 19s flaps are doing with usage? I saw the thread with someone comparing the flap and it is thinner, however I'm more curious to see how everyone is doing with color transfer and if owners think the iridescence will fade off with wear. Any thoughts or experience? I'm not not sure if it would hold up to be worth the cost of the bag. I would only be using the bag for special occasions/weekends.
