BMI v. Reality

Kennedy • Math/Science Teacher
I'm 5' 3" and weigh 180. I don't look obese but my BMI is 31 so by its standards, I am. It's really made my self esteem go way down since I never considered myself obese. 
​Here's a pic to show what my body looks like. (Yes it's a Halloween costume lol)  
​Anyone else have this problem with their BMI results and the way they actually look?
