Cut out the toe part of your sock.
Roll the sock into a donut.
Put your hair in a ponytail. How high you make your ponytail that's how high the bun will be.
Insert the sock through the ponytail.
Separate hair into 2 parts.
Then using a brush spread hair to cover the sock.
Add small hair ties and twist the remainder of the hair very very tight and tuck under sock.
Finished look! Perfect elegant Bun :-)
