This alien onesie is great. It fits perfectly and is extreme comfortable for the winter. It is nice and warm and keeps me toasty. The design is cool, it zips up and down it is green and the hoodie has the face and ears of the alien. My daughter loves it. The onesie came smelling fresh and nicely wrapped. Great coat for the money. ... show more
