Reviewers do say they run small, so order one size up. 

Promising review: “I love these pants, and I think that if you need one item in your closet, it would be the Melina pants. I’m 5’3″ and bought the regular length thinking that the short length would be too short, but I was wrong. Good thing about the style of these pants, you can get them tailored and the look won’t change. They do fit slightly smaller, but when I put them on today, they were loose so I’m assuming it’s because I stretched them out. After buying leather pants from multiple clothing brands, the Melina pants are the only pair that stretch and don’t stick to you weird when you sweat.” —Amy

Get them from Aritzia for $148 (available in sizes 00–16, short, regular, tall, and in 26 colors).
