Wow! It looks like a texture similar to fish scales ... love it! Very pretty. And 60 hours making the circles, omg! I would've gone mental, I'm crazy impatient working on my sewing projects.
As for the number of them, I'm guessing 180-200 circles (please update soon with the number!).
I also want to know is how heavy it is!
Ah, I'm feeling inspired to make a dress like this myself!
