When temperatures climb past "tolerable," the last thing anyone wants to wear is a pair of stiff, clingy jeans. So, what do you wear when it's too hot to think, let alone get dresses?

Just look at celebrities like Jennifer Lopez and Hailey Bieber, both of whom have swapped denim for lightweight pants that look effortlessly cool. From flowy linen trousers to parachute styles, we rounded up easy-going bottoms that'll serve as your unofficial uniform of heatwave season.
