Old Navy 6-12 months Cowgirl Costume fits like 3 to 9 months

This really cute two piece costume includes a long sleeve onesie and velour pants with fringe. The onesie has brown and pink screenprinting that resembles a vest and handkerchief tied at the neck, 2 snaps on the left shoulder, and 3 snaps on the crotch. The pants are made of a luxurious velour that is white with light pink cowprints and fringe. The waist is all elastic. It is in perfect condition. My daughter wore this at a Halloween event with nothing underneath when she was wearing 3-6 months clothes, and it was roomy. We tried it on now that she is wearing 12 month clothes, and the top (onesie) still fits fine, including being long enough in the crotch. The pants still fit in the waist but they are about 1.5 inches too short. Weighs 5.7 oz.
