  • Adorable!
Size: Medium Color: Blue Onesie
I got this for my son for Halloween. He loved it! It is definitely a comfy fit. He was warm during trick or treat and got so many compliments. He now uses it for pajamas. So win win over here!

  • PLEASE IGNORE THE SIZING INSTRUCTIONS!!
Size: XX-Large Color: Blue Onesie
The onesie itself is well-made, and a good-value. It is comfortable, and looks like the product photos. The big-problem is in the sizing-suggestions, both from Amazon and also the product listing. I purchased a different character costume, from another vendor, in my regular size-large, and received a costume that was far too snug. So with this costume, I went against the sizing-instructions, which would have placed me (5-foot 7, 155 lbs) as a "medium", I believe. Instead, (thankfully) I ordered an XXL, which fit perfectly! So, to sum up; if you want the costume to fit like thermal-underwear, you can follow the sizing-chart. But, if you want the costume to fit like it does on the models in the product-photos; you need to order two sizes above the size you normally wear! ... show more
