Runs extremely small.. based on reviewers warning to purchase a size up, I did. I wear a regular XL so I purchased a 2xl, figuring I could cinch with the adjustment buttons if it was too baggy. No.. not baggy.. it won't even button! Also, its not a light weight fabric.. I would not recommend for summer months. I like the style however, so I will keep it since I am dieting and Ill wear it next fall.
Get two sizes up. Not lightweight .
