Take your measurements with a soft tape held level and comfortably close to the body. Compare them to the individual style, then use the product’s model and fit notes to decide how much room you want.
If two sizes could work, consider the intended shape and fabric. Select the roomier option for a relaxed line or if you prefer layering; select the closer option only when the product notes support it.
