Ordered my size, but they fit baggy

Let me start with what's good about this pants. it's true size with a bit of stretch to it. the pants look exactly as it is in the picture. The only thing I did not like about it is that it has a fishy smell and tbh every leather piece I order from Fashionnova has that fishy smell and let me tell you it has to do with the material and am not upset about it. I gets rid of the fishy smell by soaking the piece/ pieces in vinegar, warm water, baking soda and a splash of soap ( Let it soak for 30 minutes, if the smell is still there just repeat the steps until the fishy scent is gone) I advise you to air dry any leather pieces as the washer and drier can damage them.
