Trade a 2005 Old Navy fuzzy bear costume 0-3 (need) for 3-6 (have)?

[jda312]

I bought an adorable Old Navy soft furry bear costume (3-6 months) this year for my baby girl, who will be 6 months old come Halloween. However, she is small, and I really NEED the 0-3 months size. I tried to get ON to locate it for me, but they said it's completely sold out. Perhaps, someone on this board bought a 0-3 and NEEDS a 3-6...baby bigger than expected?
