This has only been worn once! I got this brand new this past spring, I only wore it once. It’s so darling, I just haven’t found myself reaching for it- it’s too cute to just sit in a drawer full of other pajamas! Both top and bottom are a size large, I’m typically a small to medium and this fit me just fine, both top and bottom are a louse silhouette anyway so anyone from a size S-L could pull this off well. The straps are adjustable on the tank and the waistband is stretchy elastic on the shorts.
