Use clear elastic to tie a ponytail and divide the ponytail into 2 segments.
Take a small strand from outside of one strand and drag it across to other strand. Pull tight and keep the two main strands separated. Don't worry if it looks messy, the look here is ultimately distressed. Tip: Use smaller segments to hair for a more dramatic fishtail braid.
Tip: Purchase a fake ponytail at a beauty supply store to practice on.
Tie off the braid with elastic and snip the upper elastic. Pull at braid a bit to create a distressed look.
