Get the look: Rachel McAdams at the Sherlock Holmes Premiere

We love Rachel McAdams' hair at the Sherlock Holmes premiere last week; but hers isn't the first long braid we've envied lately.  A style like this would work great this winter especially when you need to wear a hat.  The look here is elegant but unstructured and with Sebastian stylist Thomas Dunkin, we can do it ourselves:

1. Start by applying a volumizing product like Sebastian Professional Texturizer to wet hair.
2. Blow dry in sections, and pin each section in medium and large sized Velcro rollers throughout whole head and allow to set for 5-10 minutes.
3. Allow to cool then take down rollers, and spray hair with a dry shampoo for added texture.
4. Emulsify a small dab of Sebastian Professional Microweb Fiber between palms and run through top of hair. Backcomb front section and manipulate for height and volume. Secure with pins.
5. French braid bottom half of hair starting behind left ear and pin random remaining pieces into braid for haphazard, playful positioning.
6. Finish the look with Sebastian Professional Shaper Fierce for tousled movement and controlled hold.
