The Prince of Sweetness, aka my grandson, is going to be Batman for Halloween so this sweater has nothing to do with that specific evening. I hope he will enjoy it while playing outside regardless of the date.
The sweater pattern is for sizes 2, 4, 6 or 8. I used inexpensive acrylic yarn as I don't intend for this to be an heirloom garment. My grandson is warm much of the time anyway (unlike me!) so I don't know how much wear this will get before he outgrows it.
