Katy Perry looks like she should be serving milkshakes on roller skates. Celeb hairstylist and Artist Director for MATRIX, Nick Stenson, shows us how to get the look:

1. Apply a texturizing foam to damp hair.

2. Blow dry your hair with a round brush.

3. Using a 1-inch curling iron, create an off-base rope curl. An off-base rope curl is when hair is smooth at the roots and curled from the middle of your hair to the end of your hair.

4. Create a triangular section in the front part of your hair. Make the section by taking hair from the corner of your eye to the corner of your other eye about 1-inch back from the hairline.

5. Brush this section forward and roll underneath, creating a vintage roll. Pin in place.

6. Spray the entire look with a strong-hold hairspray.
