A pile of spaghetti! This would be super easy to make.
Mermaid. I'm not sure I would ever dress a baby in a two piece but this is adorable!
Angel - this would also be fairly easy to make. Grab a white dress, bend coat hangers into wings and stretch white tights over the hanger form. Bend another wire into a "halo" and attach it to the back of the costume.
Lady Bug - also easy to make. Go to any craft store and buy a lot of red tulle. Tie it around a piece of elastic (for the waist). Then cut out black felt spots to glue to the tulle skirt. Add a black top and black pipe cleaners to a head band.
Taco/Burrito (I'm not sure why the first is wearing a mustache but it is so stinkin' adorable!)
Ummm...baby aerobic instructor?
My mom loved this movie! This baby is dressing up like Wilson the volleyball from the movie Castaway.
