When I first tried this, I was expecting to be underwhelmed and kinda rolled my eyes at the description, but it turns out that I really love this scent. Lady Vengeance is actually my favorite rose fragrance.
Lady Vengeance isn't perfumey or sharp or overly sweet. The vanilla smells cool and clean, with a subtle sweetness. The rose is dry & gothic smelling and has a very "I am a sensual and confident woman" sense for me. And the patchouli doesn't smell like patchouli at all to me, but there's something almost masculine here, like a whiff of leather jacket and shaving cream underneath the vanilla and rose.
It's confident, cool and classy, but also sensual and mysterious, and it has this total edge to it that says "don't mess with me." It's just the right mix of sweet and clean elements with a darker slice to it.
