The size that I ordered ended up being out of stock after my purchase went through.  The company called me to ask if I either wanted a larger size or to cancel the order. I chose the larger size, and it was a blessing in disguise! The larger size fit perfectly.  I would recommend ordering a size up if there is any question about what size to buy, especially if your child is tall.  Also wanted to compliment the company. Their customer service was exceptional.
