These Pj's are just adorable and they fit my son well. They do not shrink when you wash them so I don't have to worry about him wearing them once and then them not fitting. They are made so well too, a thicker material like cotton that is not thin at all. They are pefect for cold weather and even though it is January he still wears them all the time. We have had them for months and they have been washed many many times and the shirt still glows in the dark really well. They are awesome.
