    • Our little gremlin's first Halloween
Review Image by hunter hunter
We thought this costume was super adorable! It was easy to put on, and the snaps made diaper changes not too bad. It was heavy enough to keep her warm outside but not too heavy to overheat her inside. The ears were kind of folded in from the packaging and didn't really straighten out unless we held them out, but overall that wasn't a big issue. We only put the hat on her when we answered the door to hand out candy. We got the 6-12 month size and it fit well. She was about 7 months at the time and very tall wearing mostly 9 month onsies. It says to hand wash, but I did run this through our washer on a cold delicate cycle, line dried it, and it held up just fine. Overall, would recommend! ... show more

Got this for my 10 month old and it was perfect! She didn’t mind wearing the head piece at all. Nice and cozy for cold weather

    • So comfy
I bought this for my son who is an 18 month clothing and he still had a room to wear something warm underneath! So it runs a little bit big. But this was absolutely fantastic. It was so warm and cuddly and cozy. We put him in sweats underneath but to be honest we really didn’t even need to do that. Def recommend. ... show more
