One of my favorite hairstyles that Lydia Martin wore on Teen Wolf was the Milkmaid Braid. Always a classic, it's so easy and effortless to do because all you have to do is make two braids then pin them up. You can leave hair out if you want but you don't have to.
It's definitely a good summer hair style especially when it's really hot and I want to do something different besides putting my hair up in a ponytail. This is such an easy, go-to style.
