"Knix's Evolution bra is the most comfortable bra I own. It's the kind of bra that, with some smart planning, can be the only bra you bring on any entire trip. It's wireless but supportive—great for plane rides. It's reversible, in black and beige, so it goes with a variety of tops. And it molds to your body over time, making it so comfortable that I sometimes forget I even have a bra on. If you prefer padding, their Wingwoman bra is fantastic, too, and their Longevity sports bra is my current favorite workout bra. It's a cropped length but doesn't bunch up at all, making it great for hiking trips."
