For instance, I don't like two patterns next to each other. I don't like two or more metals together in a piece of jewelry. I don't like things that drape a lot, like dolman sleeves or ponchos or cowl necks. While animal prints don't bother me (unless combined with other prints, as I mentioned first), images of animals (pandas, tigers, etc.) on adult clothing DO bother me.
I don't like slouchy boots. I don't like slouchy socks. I don't like athletic clothes from the 1980's.
I don't know if that's an exhaustive list, but it's a start.
