Yes, 
 
Yours is better. I don't know why there is a hole on your scabbard. 
From what I have seen on just a few old West Sumba pictures I can't see any major difference in dress.  
But I am neither a fashion nor a Sumba expert. 
Try to find the book Islands and Ancestors by Newton & Barbier if you want to learn more about West Sumba, as well as the culture of other islands. 
 
Good luck, 
 
Michael
