This Halloween costume was so cute. Its a little small, but not much. I usually wear a 6-8 and I sized up and am glad that I did. The fabric is thin, so I wore leggings and a camisole underneath the costume which made the costume feel a little tighter. If you're going to attend a wild Halloween party, be careful that you don't rip this costume. However, walking my kids around the neighborhood and carrying my infant all night, this costume held up just fine.
