 Overview of the costum of the Rhodopes, South Bulgaria  
  Hello all, 
This is the last installment of my series on the overview of Bulgarian costume. This covers the south of the country, specifically the cultural regions of Pirin and Rodop [Rhodope].
 This includes the oblasts of Blagoevgrad, Smoljan and Krdzhali, as  well as the southern parts of the oblasts of Pazardzik and Khaskovo.
The majority of the costumes of this region are of the saya type, with just a couple locations having the sukman type. 


Pirin Region

Blagoevgrad Oblast


 This is Bulgarian Macedonia. The borders do not exactly match the extent of the Pirin cultural region, as I would exclude both of the eastern corners, but it is close enough. 
Pirin mountain lies in the center of this oblast, which thus is naturally divided into four districts. In the northeast, Razlog district, in the northwest, Blagoevgrad district, in the southwest, Sandanski district, and in the southeast, Gotse Delchev district.
