SLEEK & TIGHT
There's a reason ballerinas are partial to the tight bun. You can work up quite a sweat and still not have a hair out of place. This version, perched high on the head, is simple to do with long hair that's not too layered. First, comb a generous amount of styling cream through dry hair, from the roots to the ends. (Kiehl's Creme with Silk Groom, $18, adds beautiful shine without looking greasy. If your hair is wet, use a gel instead. Try Aveda Confixor Liquid Gel, $17.) Then brush your hair back and up, pulling it taut with each stroke, and fasten it into a ponytail (because you want it supertight, you might want to use a hair "bungee," like Rickycare Invisipin Bungee, $5 for four, that you can wrap as many times as you need to and then hook). Coil the length of the tail around the elastic and secure it with two or three bobby pins. A little hairspray at the hairline will tame flyaways. Dress, Donna Karan New York. Earrings, By Boe.
