My 2year old son has recently become obsessed with the ninja turtles. He just had to have the costume for Halloween. Well i went to every store in my town looking for a costume and all i could find was teenage boy sizes. Amazon never fails to disappoint.  They not only had the size i needed but could get it to me overnight for halloween. My Son went crazy over his costume and i haven't been able to get it off him yet. Hes two but i did order the 3T-4T because i wanted him to be able to wear it awhile for play and hes taller than normal 2 year olds.  I would definitely recommend this to other mothers.
