Halloween costumes rarely come any simpler than they do in the form of Juno MacGuff's pregnancy-friendly ensembles. Consisting mainly of jeans, t-shirts, and various zip-up sweatshirts, her look is super casual and, lucky for you, super comfy (assuming you?re not a pregnant teen yourself). To achieve that distinctive Juno vibe, however, make sure that your hoodie is of a darker, muted solid color; that your t-shirt is a trademark orange/white striped deal or some obscure vintage design; that your hair is tied up in a whimsical ponytail; and, of course, that you've secured an appropriately womb-sized pillow beneath your t-shirt. For funsies, bring your own jug of Sunny D to swill throughout the night. Oh, and if you plan on making conversation with anyone, make sure you've got plenty of esoteric pop culture references and cleverly phrased witticisms at the ready.
