For a padded jacket, where the hem is about mid-thigh length, if you point your legs to the inside of the jacket, you will have better range of motion. If you point to the outside front of the jacket, the jacket itself will interfere with range of motion and fit of the chausses. From the outside, it will also cause your chausses to pin the jacket to the front of your legs, which you want to avoid. The jacket should hang over the front of the chausses instead. Or just use a seprate vest but we know that's not really historical.
