I just saw the pics of your collection again. I truly don't feel so bad about my collection anymore. BUT, despite my large collection, I just got into eyeshadow palettes and now I can't seem to stop buying them. I read all the reviews first and if I TRULY can't get a product off my mind, I buy it. My collection is not even close to being as big as yours, but it's big. For me, personally, the MAC lip glasses go bad a lot more quickly than NARS, Buxom or Dior. I have discovered that Chanel glosses don't hold up well over a couple of years either and they should for what they cost.
I feel sad because my MAC shadows, which IMO are the BEST and which I have almost every color of, are going unused while my UD palettes, my Too Faced palettes and Stila palettes get all the love. When I use my MAC shadows, I'm reminded why they're the only ones I used for so long. Anyway, great collection. Really does belong in a museum. I would definitely pay good money if there were a makeup museum, beauty product museum. I love makeup and I love my beauty products. I'm a junkie and nobody gets it. Except the people on here!
