These are made of a soft, stretchy fabric that is thick enough to hold its shape. Please use the size guide below for selecting the correct size. It is my opinion that they fit true to size, with that being said please have a look at the size guide. Also please note that the drawstring is for esthetic purposes and these shorts do have an elastic waistband. I have provided an info box in the listing if you want to leave any extra information about size. For example a smaller size shirt than shorts.
