I have made up a few pair of armitas in the last week or so.
These are a more traditional pair of no hardware armtias, the waist is a wrap & tie and the legs are done up with rolled leather buttons.
Here is a pair of shotguns with an armita apron, the waist is a strap & buckle, the zipper is laced in on the outside of the legs. This can keep the zipper away from the fringe and make them a little easier to do up.
These armtias are a little more modern in style, the apron does not fold over, the waist is strap & buckle and the legs are done up with snaps and rings.
Just a close up photo to illustrate how the apron is made.
