A simple and chic hairstyle for this Fall is the knot bun. The knot bun is sexy yet sophisticated. This new fall trend hairstyle can go with any occasion. You can “tie the knot” at a party, club, date night, or just to hang out. This hair style is easy to do and does not take much maintenance. To do the knot hair style: blow dry hair straight, create either a clean center or side part, secure hair in a ponytail, then wrap your hair around in a loop with the ends pointing up or tucked under, a round ballet bun, or the classic double knot.
