Item: Old Navy Tie-Belt Dolman-Sleeve Jumpsuit in Black and White Stripes ($29, originally $40)
What our editor said: "This jumpsuit is the holy grail of one-piece attire. Made from a rayon-spandex blend, I can sit at my desk all day long in this jumpsuit and it doesn't wrinkle. That also means it's great for trips, whether you're wearing it on a long plane ride or folding it into a suitcase. The wide-leg cut is incredibly comfy; it practically feels like you're wearing pajamas. Did I mention it's flattering? The fabric smooths out my stomach, and the tie belt cinches my waist. I'm starting to think it was woven with magic or something." — MW
