I have long legs too (but I'm only 5'4)
My favorites right now are
American Eagle their longs are usually 34" inseam..Old Navy is usually 36" inseam for Tall so you might find you like the length @ AE. I have the
Straight and the
Boyfriend. I find the boyfriend to be a little too low rise for my liking but they fit well. They run pretty true to size so I'm pretty comfy ordering online.
I've heard great things about
Buckle jeans too but I've never tried them. I find they are a bit too $$ for my taste
