Test Text1 italics Test Text1 plain Everyone could use a good makeover every now and then. Especially when you're going through a change in your life, like becoming a beautiful, new mom, graduating from school. We went with abc's sara haines to find a couple of real women who fit the bill to give them a glamorous, new look. Reporter: Right now, we're in downtown new york city. And we're about to ambush one of their waitresses, emerald, for a makeover. She has no idea we're here. Come on. We're here to tell you about a makeover. Emerald knox is a first-time mom to 1-year-old johannes and constantly on the go. She's hoping to update her mommy look to what she calls sexy fierce. Now, it's sasha's turn. Hi. We're going to make you over. On "good morning america." Oh, my gosh. Reporter: Sasha is a 21-year-old premed student at fordham university. She's ready to trade in her casual coed apparel for a more professional physician-appropriate look. We're here. Woo. Come on, guys. Time to shop until we drop. We head to marshalls and meet style expert, allison. I want to add some color into your wardrobe. And blues and greens and purples are really strong for fall. Reporter: Next, we hit our times square studios for hair and makeup. Sasha, with lara's glam squad, greg and andrea. And emerald, with robin's glam squad, elena and petula. Now, we give them time to work their magic. Now, the moment we've been waiting for. Let's get to the big reveal. Emerald, come on out. Oh, my gosh. I mean, fabulous look. Designer brands head-to-toe. Studded envelope clutch, the jacket. And that gray jean, the new black. Tell me what you did with her, with hair and makeup. With the hair, I added a little bit of color. So she could have a little light in her life. And I added some lashes to her. And you notice, she has a little green mascara. That's the trend. We're going for number two right now. Let's invite sasha out here. I think the fact the moment she walks in for an interview, no need to try out, you got the job. This look, it's so fantastic. And chic. Just take off the leather jacket and she's ready for a night out. We laired her hair. And we pumped up the color to give her more brightness. And the makeup, we did a jell eye liner to last longer. I think the glam squad, totally nailed it. Totally nailed it. You look beautiful. A big round of applause from everyone here. They were looking good before. And lara and I know how lucky we are each and every day. We want to thank marshall's style expert, allison. And thanks to marshalls for sponsoring and providing the clothes for this segment.
