I have a problem with pants...? Long legs?

I have long legs and it's getting to the point where it's annoying. Whenever I buy slacks or jeans I always have to get the long sizes, and that's okay because most of the time they're long enough. My issue is with sweats and PJ pants. They always stop like an inch or two over my foot, and it looks horrible! Where can I go to buy pants that will actually fit my legs?
