Cook and author Alison Roman has become something of a champion for millennials who prefer hanging out over going out. Her unfussy approach to cooking—coupled with her highly authentic persona—landed her a food column in The New York Times, two successful cookbooks with two more on the way, and thousands of adoring Instagram followers. This week, Alison sits down with Perrie to talk about food, yes, but also personal style and the items she feels most comfortable wearing, the (very) expensive bag she’s dying for but can’t justify, and the outdated fashion “rule” nobody should follow. Alison and Perrie also get into dating deal-breakers, how her feelings about food and relationships can’t always be separated, and the thing she’ll never do on a first—or second—date.     For more on this episode, visit www.glamour.com/whatiworewhen   Find Alison Roman’s cookbooks, Nothing Fancy (a current New York Times bestseller) and Dining In, in bookstores and online, and look for her columns in Bon Appétit and The New York Times.
