Knee breehces, used by most armies in the Napoleonic period for full dress, both for infantry and cavalry. Those pictured are for officers, with side pockets, while generally those for other ranks had no pockets. Also, in many armies private soldiers breeches had no knee straps for buckles but closed with either a string or button. These breeches can be made in wool cloth, or else linen, hemp or cotton for summer undress wear. Available in standard sizes but better if you take your own measures.
