Step 1: Part hair from ear-to-ear into a top and a bottom section.
Step 2: Secure top section with a ponytail holder.
Step 3: Take the point of a rattail comb and put it under the hair, just at the crown. Gently coax hair up until it's just a bit puffed.
Step 4: For more drama, wrap a ribbon or a strip of fabric around hair and fasten with a bobby pin.
