Here is Horodenka district within the Oblast.

This woman has decided to do hers in black, to reflect her age.
Here is a famous photograph showing a bride with two bridesmaids. if you look carefully, you will see that each is wearing a chemise with one of the above designs. From left to right, 'wings', 'circles' and 'flies'.
Traditionally, a wraparound overskirt 'obhortka' was worn, the corners tucked into the sash, and a vertically pleated apron worn in front. This was replaced later on, at least for less formal attire with a skirt and gathered apron as you can see here above.
A multiplicity of gerdans [beaded necklaces] were worn, both around the neck and on the head, as well as other jewelry. Brides wore complex crowns with hanging ribbons, and married women wore kerchiefs which replaced the earlier namitky.
The unique vests are cut straight, trimmed with ribbon, and are usually a plain blue, red or black, although sometimes they were made with patterned material, as we see here worn by this bride in 1945
Here are a few older photographs from this village, likely from the turn of the 20th cent.. These show the older men's outfits, and seem to indicate that the distinctive vest was adopted later, likely in the 1920's or 30's.
