My daughter wore this for this last haloween when she was 16 months. She has a very small stature and it still fit her pretty good (but plenty of room so likely great for larger kids) and it didn't look to baggy. She loves to play with the antenna even now months after haloween. My only complaint is that the wings could have a little bit of stiffness to help them stick out better from the back and the design on them fades if it gets rubbed very much. You'll need a black shirt and tights (and even shoes)to wear with this though. But as long as you make sure you have those things on hand then your kid with look cute as a bug!
