"do end immediately above my knee." "baggy" and not figure hugging - should be fine. As long as you look professional, there should be no issues. Maybe do try not to have overly revealing blouses, like I've seen some women in official meetings. Those examples you posted in the photos should be fine.

You will only know when you get here n start working. So, suggest you don't get a new wardrobe just yet.
