Start with completely dry, well-brushed hair. Gather your hair loosely toward the nape of your neck and comb through with your fingers to give it an undone soft texture.
Create a low, loose ponytail and secure with a hair elastic.
Make a simple knot by creating a large loop near the base of the ponytail and pulling the ends of the ponytail through the loop. This will create a large knot at the base of your ponytail.
Use a bobby pin or two (or more if you have very thick hair) underneath the base of the knot to secure it into place. Finish off the look with a medium-hold hairspray.
