I uploaded some folk costumes, but they are not the museum’s high profile exhibit. For people who like their art really old, here are some items from the popular antiquity floor of the National History Museum (all items it hosts were excavated in Bulgaria). These are Thracian in origin and are from sets from around 4th century bc. The 24-karat gold set from the last photos was very hard to photograph because it is so shiny it messes up the photo, so I only got good pics of 3 of the items. But you can see more on Wikipedia.
