Start with your hair in dual Dutch braids. French braids might work too, but I find Dutch braids with the distinct braid-part showing works well for this.
Braid a long, thin scarf into the thinnest braid.
Cross the braids in the neck and wrap the braid without the scarf around your head. If you can tuck it under well enough, you don’t need any pins to secure it.
Wrap the braid with the scarf around your head and make sure you have the second braid over the first braid to pin it in.
Wrap the scarf around the tassel (Not necessary I guess, but I think the end result is sleeker and prettier)
If the scarf is very long, wrap it around your head with the braids. If not, pull the scarf under your braids.
I like taking the scarf around in the shape of an infinity sign. And done!
Just because I felt like it, I matched my toenails to the scarf! (Metallic tone in the polish made it hard to capture)
