Celebrity stylist Annabel Tollman shares her secrets to making A-list celebrities like Scarlett Johansson look their best on the red carpet. "I always look at their body shape first and foremost," she tells Rachael. "We need to sort of always dress to flatter." Annabel adds that she also tries to match an outfit to a celebrity's personality: "What you’re really trying to do is make their outside look like their inside."

For the average woman, Annabel points out that having an A-list look is not out of reach. "There’s something for everybody out there, it just takes some time and some dedication," she says, adding that you need to prepare your look like you would an important meal. "You wouldn’t have people over for dinner and just go to the kitchen and open the cupboard and not have any ideas," Annabel explains. "Just as you want to learn your recipes, you need to learn things like what you can do with a long dress or a t-shirt dress look, how you can do variations on it like change the colors. And practice your looks; you wouldn’t try a recipe for the first time when people are about to walk through your door, so when I’m working with my clients, we do a fitting a week beforehand so you sort of know what you’re in for. It takes away that anxiety."
