Hey girlie! Usually when I buy my trousers, I have to go up a size so they aren’t too tight around my hips and give me a little of a relaxed fit. So I’m guessing that means they run small and would fit you good because you’re petite 🙂 I’ve bought trousers from American Apparel, Urban Outfitters, H&M, Zara and thrift stores. You should look into petite brands and stores that would cater perfectly to your needs 🙂
