The perfect length for an ankle pant is when the pant covers the ankle, or the ankle just slightly shows. The Lafayette fashion show got it right. Their models wore the correct length with those pants. When the pant length is too short, it looks dowdy and makes the person look heavy.
For wide leg pants, hems should just touch the top of the shoe. They should not puddle or break (which means the pant folds on the shoe). The only pant with a break or that slightly puddles is one with a straight full leg.
