To-do list:
1. Pin this picture of Michelle Williams in the new Louis Vuitton ad campaign and take to hair salon. Note: important detail of jaggy undercut above the ear.
2. Invest in appropriately texture-enhancing hair product (and plum lip pencil and nail polish).
3. Mentally bow down to fashion superstar hairdresser Sam McKnight for creating the tomboyish, '90s look – he was a fave of Grandma Princess Di, doncha know.
