So, I wore braids all day while out and about just to see whether I would get a decent curl out of it. I french braided my hair pretty tightly, and my hair takes a curl very easily.
My veridict is sloppy waves with little to no curl. I don't really recommend it, and it was sort of a lot of anticipation for nothing. (Please excuse my makeup-free face and let me know what your experiences are in the comments!)
