I had been wanting to try this for years and never got around to it until recently. It is actually much more simple than you would imagine.
All you have to do is start like you are making a pony tail, but then don’t pull the tail through, so that it is stuck looking like a sloppy bun. Then you take the end and pull in forward and tuck it in to hide the hair tie. You can use a couple bobby pins to hold it there.
It is super easy, I can’t explain it that well. I wore it this way a few times this summer, and I always got compliments! It is very high fashion but at the same time lazy. It is great if you are low key about things like I am, and when it is freaking hot outside and you just need to throw your hair up, you can do this and still look fashionably cool.
