 Hi Kara  cuteness!  SIZE: waist-wise, it fits up to a girl's size 10/12 or a boy's size 8/10 (you can see our 55-lb son in the photo wearing it) height-wise, adjustable straps accomodate for various heights (ie. our 3-yr-old daughter wears it occassionally after I quickly shorten the straps) clean & allergen-free (smoking-free & pet-free & even gluten-free home) . . . it's ready-to-play-in |
