I'm 5'11 and buy sweatpants and most of my work pants from the JC Penney Catalog. If you give them your e-mail address they often send free shipping emails. The Nike perfect fit workout pant comes in a long, and they are great. You can get those from Nordstrom.com. I also love the basic work pants from Ann Taylor Loft. There are a couple of websites that sell speciality tall women's clothing but I find they are a bit expensive. I read that Lululemon are Gabby Reece's favorite and she is 6'3 or something, so they must be super long.
