Antique Oaxaca, Mexico Triqui garment

This is a vintage huipil from Oaxaca, Mexico made by an indigenous Triqui woman.  There are probably 400 hours of work in this huipil.  The 3 panels were woven on a back-strap loom from natural brown Coyuchi cotton.  The ribbons, depending on how they are tied, may symbolize whether a woman is single or married.  32" wide and 42" long from shoulder to hem on each side.  A very collectible piece.
