A fishtail braid gives a high bun a textured, intricate look suited for picture days and formal occasions. Gather all hair into a sleek high ponytail at the crown. Divide the ponytail into two equal halves. Take a thin strand from the outside of the left half and cross it over to the inside of the right half, then take a thin strand from the outside of the right half and cross it to the left. Repeat down the entire tail, secure with an elastic, and pancake slightly. Wrap the wide fishtail braid around the base to create a flat, rose-like top knot, securing with decorative pearl-topped hair pins.
