Fall-front 18th century breeches
18th century fall front breeches, here illustrated are original ones of the Swedish army, but any other army and unit (Prussian, Hessian, etc.) can really be reconstructed.
They are made of wool cloth faced with natural linen or hemp, buttons of pewter or brass.
Available in standard waist sizes and inseam lengths, as they were meant to be rather full around the seat and crotch, to allow for movement, sitting, riding, etc.
