"If there's a brand that can get us to wear 'real clothes' on a plane, it's Universal Standard. With clothes from size 00 to 40, its mission is to create clothing that looks and feels good on every body, using fabrics like premium Peruvian cotton, soft Italian Merino wool, and French satin-back crepe to do so. The Promenade linen jumpsuit could easily be worn all day long, and the Sally Liquid Jersey shirt dress is a piece you'll wear again and again. As for the jeans, before you shake your head, know that the brand's styles are stretchy, with a truly relaxed, comfortable fit—look to the ComfortDenim collection for the most plane-friendly pieces. If jeans are a no-go (fair), try the Go-Stretch pant for a looser waistband."
