There are fine examples from Guatemala, Laos (including Hmong), San Blas Islands (molas) and India. The needlework done by hand in these pieces in incredible. Due to globalization, this refinement of needlework in tribal garments is becoming scarcer and scarcer.
The Guatemalan textiles are handwoven. The narrow fajas(belts) and huipiles (blouses) are woven by women on backstrap looms, a painstaking and slow process. Each village in Guatemala has its own particular design, which will vary some with each weaver, but within limits. Someone who knows Guatemalan textiles well can go to a large market and identify which village a woman is from by the design of her woven clothing. The cortes (skirts) are woven on large floor looms.
Molas come from the San Blas islands off the coast of Panama. There are two groups of molas. The first group is in perfect condition and was made for sale to people outside the Cuna (San Blas Islands) culture. The second group was bought by one person directly from the Cunas in the 1980's and is unusual because all molas in that group were actually worn by Cuna women. Most of those are more primitive in design and show varying degrees of wear. Many have fabric layers which are prints rather than solid colors and this is something I have never seen in molas for the trade. These printed fabrics add an exta dimension of vitality to those molas.
The Hmongs are an ethnic group living in the mountainous areas of Laos, Vietnam, Myanmar, and Thailand. The Hmong textiles for sale here are pieces which have been worn.
The Indian textiles include a large group of chaklas, also called mirror cloth because of the many tiny round mirrors stitched onto the surface, which is then heavily embroidered. These, and torans, which are hanging chaklas which can be hung over doors and windows, are up to 20 years old and form a very important part of a girl's dowry. Fine pieces like these have become scarce because so many were destroyed by the severe earthquake in Gujarat Province over a decade ago.
