Where are the pants for tall women?

My daughter is a recent college graduate and is job hunting. She is 6' tall, and prefers to wear jeans and palazzo pants in her daily life, all of which tend to be a bit short on her. But she's now going on interviews that require "professional" attire. Every pair of professional trousers is a good 3-4" too short on her. Even the things that are listed as tall or long are still too short. I have suggested skirts, but she's not comfortable with that (at least not yet). Before she transitioned we were buying her 34" inseam pants/jeans. This can't be a problem only she is having. Tall ladies, please let me know where you shop. We'd be so, so, grateful!
