Kate Walsh arrived at Legion's Sundance Film Festival premiere looking enviably glam-casual, with understated makeup and a sweet, messy bun that looked easy and red carpet appropriate at the same time. I think this look would be absolutely perfect for Valentine's Day or a date night—some time you want to look sophisticated but romantic.
To begin, spray wet hair with a lightweight styling spray, like David Babaii Mise En Plise Light Styling Spray ($12.95). Then, blow dry at least semistraight, adding your flat iron if you need it. Once your hair is dry, separate the very front sections (from right above your ear forward) from the rest of your hair, and pin everything but those back into a simple bun at the nape of your neck. Take a large barrel curling iron (about one and a half inches) and lightly curl the front sections. If your hair is fine or doesn't take a curl well, spray on some hairspray, like Extra Hold Hair Spray by Nivea ($9.50), before you curl to help keep the look together. For everyone else, after you've curled, run your fingers through a couple of times to loosen the curls up, spritz on some hairspray if you'd like, and you're ready to go.
