I am carrying my Shoulder Tote in Khaki with Vachetta leather trim today and it doesn't look quite right. I was told that Vachetta turns into a golden brown color but mine looks a little orange at this point. I was also told not to treat Vachetta since it ages and forms a patina. What are your experiences with Coach vachetta? By the way, this bag was given to me a year ago and I do really love it. Just want to make sure I am doing the right thing with the vachetta. Thanks!!!!!!
