FIT Models Measurements: Height 5'3 Waist 31", Bottom/Hips 47" Model wearing size Medium Fits true to size Moderate Stretch, but No elastic in waistband so waist band stretch has less stretch potential than the body of the pants. If your midsection is a problem area for you keep this in mind and size accordingly. Shorts only have a slight amount of stretch in the body so kea wouldn't really suggest sizing down, she feels they're a bit snug in the waist
Don't exceed any of models measurements in size medium or they may not close properly
