Megaflorals tend to smell like wet dog on my skin for some reason, with some exceptions, such as Yves Saint Laurent Paris and Chanel N5. Creed Love in White turns nasty within five minutes on me, and this makes me sad because I love how it smells in the bottle. This also happened with a couple others that had a great many flowers as top notes, and would be classified as florals, but I don't remember what they were since I didn't care for them anyway. Now I'm actually kind of curious about what ingredient(s) causes some of these florals to turn ugly on me.
That aside, I hate most ulrafruity scents. Escada Sunset Heat smells like a punch bowl to me. However, I like some of them--I think it has to do with whether or not it seems "synthetic" to me.
