It is very difficult to find boys shirts that fit well around the neck. A baggy shirt on your little one can ruin the entire look of his costume. The boys classic AKA shirt was perfect and didn't wrinkle. The advice I use is I always shrink my boys dress shirts just to ensure a secure neck and it doesn't affect their arm length. It just makes them shinier.
