My granddaughter wears a 5/6T so I bought the largest sold which is a 7T.  I had to give this to my 3yr old granddaughter instead because the size isn't even close.  Way too small.  Cute outfit but doesn't work for what I needed it for.  I gave this a 3 star only  because it was a waste for the granddaughter I bought if for but ok because it is still nice
