We ordered these undershirts for our daughter for the winter and also ordered a similar style from Osh Kosh (also available on Amazon Prime). I have always been a "Hanes Fan" so I was surprised how poorly the Hanes version of this undershirt fit her, as they were MUCH too short and MUCH too wide for our daughter (49" tall /52 lbs). Granted, she is on the slim side, but these are really square shaped, and I'm not sure how they would be anything but baggy on even an average girl. And if an undershirt is baggy, it isn't really doing the job of keeping her warm, is it? These might be a good choice for a husky, shorter girl but they are still cut too short, in my opinion, for the size. Conversely, I wish the Osh Kosh style had "camisole" style straps like the Hanes. However the Osh Kosh versions were a very soft cozy thicker cotton and fit her so much better (longer, slimmer, snugger) than the Hanes, that we are willing to live with the wide straps on the Osh Kosh versions and returned the Hanes for a second pack of the Osh Kosh. Bottom line: if your daughter is average to skinny, and she doesn't mind wider straps, the Osh Kosh is a better fit and softer cotton than the Hanes. If you have a "big" little girl, the Hanes may work for you, but may not stay tucked in, if you care about that.
