The word Huipil is actually a Nahuatl word, hailing from the single largest language group of Mexico.  Interestingly, almost all indigenous places in Mexico and Guatemala are Nahuatl words - even in areas where the mighty Toltecs never stepped.  

A traditional huipil from Guatemala is made from two pieces, with the most authentic pieces woven on back strap looms.  Other huipils are sewn from cotton and then elaborately embroidered by hand.

This piece was woven on a backstrap loom using a weaving and embroidery technique.  This style of Huipil is time consuming to make, taking an artist approximately 6 months, with 5 hours per day dedicated to weaving.  

This piece was woven by Maya artist Mayra Lopez of San Antonio Aguascalientes.
