My 12-month old daughter was the cutest bee I'd ever seen.  The wings detach, which is great for a toddler.  The only complaint is that the headband was not very toddler-friendly, but we just put it on for one quick picture and then took it off.  It had a lot of room to accomodate several sizes of 12-18 month olds, including my skinny daughter.  If you have a taller toddler I might go a size up.
