I like these undershirts, except they are really slim and tight fitting. Length wise they fit fine, but they're just really tight and form fitting.  The fabric does have some stretch to it, so my daughter has been able to wear them, but I would definitely size up 1 or 2 sizes if I purchased them again. Compared to the Hanes undershirts that we also own, the material of these shirts is a much better quality, I just wish they were't so tight.
