I thought I'd love Aramis Havana. I can't say I hate it, but after procuring a larger sample size than necessary because it sounded so perfect, I felt buyer's remorse. It was a let down.
Bois d' Portugal. It had great reviews, great ingredients, etc. -- really had my hopes up, but as it turned out, it is not something I'd ever feel comfortable wearing, other than at a bingo game at a hospice.
Bandit. Same story with the addition that I thought it was for men. Plus, I bought the entire bottle blind.
Amouage Reflection. The sales associate, who was very knowledgeable, kind and generous raved about it. What a horrid nightmare.
I only have real animosity toward the last. The rest, well, I didn't hate the fragrances as much as I hated being disappointed at the gap between my expectations and my reality.
