Angel Pure Shot - $115
I have some blind buys that had gone bad: Oscar pour lui, Quorum, Moustache, Halston Z14... Those former heavyweights really suck in their current incarnations.
I bought Halston Z14 recently and thought that it was just vile, but I was so stubborn that I got vintage version too. It was totally different story.
Versace's The Dreamer. Now this may be because the sprayer was broken and just leaked like crazy all over my hands instead of spraying, but I do not understand the praise for that fragrance. Smells like a grandmother to me. Good thing it was only $35. I've tried sniffing it in smaller amounts to see if my bad experience was just due to heavy leaking, but to no avail. That being said, it hasn't deterred me from blind buying at all.
