Love this tunic! I'm 5'3", 118lbs and ordered a medium based on reviews. This tunic is longer than reviews led me to believe; the medium comes easily down to mid thigh without pulling it to it's full extent. I'm keeping it either way since I planned to wear this mostly around the house with leggings. Given the loose cut, this tunic could fit a variety of sizes easily. The amount of wiggle room will for sure depend on your girth and where you carry your weight. I'm rather slim but have an Ostomy bag. Its loose enough that there is no way you could see it.
