That skirt is so cool! I like how it's a little reminiscent of a spider web - perfect season for this look.
I have no advice on the hair, I don't know what to do with my own most of the time haha. Might be fun to get a straightener to play with? I love doing a sleek straight hair look on the rare chance I do it, but I'm also a millennial so maybe that's a dated look now haha
