Black high-heeled knee high boots over tight blue jeans is really stylish.
I also wear my tall heeled boots over tight black pants and sometimes over tight or khaki pants (these pants when equestrian was in style). Blue jeans are the best pants to pair with black tall high-heeled boots, though.
I am 5'7" and have a slim body, but I think a lot of people can do this look. The high or stiletto heels are a must, especially if you are short. Kylie Minogue is short, but she looks great with jeans over boots. I copy her style for wearing tall heeled boots over jeans. Like her, I have the black Jimmy Choo pull-ons. Great, comfortable, but pricey.
