This costume is absolutely adorable! The costume opens-up for easy diaper access and all of the body parts can be taken off, should your little one dislike the hood, wings or feet. The fabric is nice and light and very soft~ with a silky inner lining. The costume is true to size but also leaves plenty of room for a long sleeve shirt, pants, etc. My 7 month old son doesn't like to overdress (he doesn't like hats, bulky sweatshirts, etc.) but I tell you, when I put this costume on him he laughed and crawled about, not letting me get my hands on him to take it off! I, eh hem- we- LOVE this costume!
