Florence, I think that's part of why I like styles on others that I don't like on myself. The broadness of any style descriptor allows people to choose the parts that work for them. This allows for more or less subtlety, tailors it to the person's body type, allows for personal expression and so on. For example, I like boho, but I like very hippie stuff and the more "ladylike" feminine boho stuff I see for sale doesn't work for me at all. But Gaylene's example of grunge was a good one. She doesn't like faded jeans, and thus, most grunge looks aren't going to be her thing. This is a very general question, though, you're right. There are definitely always going to be exceptions.
