Here's something to think about: if you could get the tie-dye Cabat new from the boutique now, would you? Or are you only considering it solely because it's currently available for the same price as the tourmaline (albeit with some scratches and used condition)? I know you already have a lilac Cabat that you love. I haven't seen any comments from you regarding either the tourmaline or tie-dye. It comes down to this, for me: pick the one you like better. Pretend that you're at the boutique, and that you try both of them on with one of your typical outfits. Don't think about which one is "better" or "a better deal." Which one simply appeals to you more? Pretend that one of them suddenly becomes unavailable, leaving you with only the remaining choice. Are you relieved that the decison-making is over, and happy with the one that remains? Or are you disappointed to be left with the one that remains?
