Here is a very very easy hairstyle even easier than the messy bun
what you will need
collect your hair into a low ponytail
take your ponytail and split it above the hair binder flip in.
that hairstyle took me seriously 20 seconds,granted when you do it it will probably look better the one I did was not a very good example,hey but you have to say it looks pretty good for having it done in 20 seconds!
This is just another version all you have to do is when you tuck it don't go all the way!
sorry this one didn't turn out so well, but trust me it usually looks better!
If you had a hard time understanding this through me a comment and I will try to make it more understandable.
