Just wanted to comment after buying my first woot shirts for my kids. The size 6 is SHORT. The sizing chart says they are 17" long and the ones we got (random 3 pack) are 16 1/2" long. After washing on cold and drying on medium, they are now 15 1/2" long! Woot, in their awesomeness, refunded me for the shirts, which might work out for my 4 year old! Just be forewarned that they are very small for a 6 and they will shrink. The 8's I ordered are more true to size.
