In June, I was at a publishing convention in New York. I saw an elegant woman with silver hair and I did not forget her braid. She had her hair pulled up high on the side of her head, braided, and laid across the top of her head.
This has become my go-to hairstyle this summer. It is simpler than the Heidi look (which I want to stop calling Heidi braids because it makes them sound quaint, costume-y, or childish). I've seen them called rainbow braids. I can do these braids (see the photos on this post), but it takes some energy and futzing.
This summer braid, however, is a snap. I pull back the front part of my hair into a barrette to help anchor the braid, then I make the braid, secure its end with a tiny, clear elastic, and pin it in place with several bobby pins. (That's as close to a tutorial as I'm getting). My hair is several inches below my shoulders, as a point of reference. I love it off my neck in the summer, and this braid is my favorite way to do that.
