Hi! Can I just ask how long arms are supposed to be? I had a teacher once tell me arms are supposed to end with one's hands on their hips, and she docked me points on a test where I used myself as a ref. My hands are about 1 hand length from my knees, and my wrists are parallel with my groin. I've noticed the mods make the arms much shorter, so I'm just wondering which is correct? Have I been wrong this whole time?
