Bought a DotM Optimus Prime costume from Target for my daughter. The mask it came w/ was too big, so I let her wear the Transformers Prime Optimus Prime mask instead (which also looks better anyway). It's her first cosplay, and she enjoyed the experience. Hopefully I can get her used to wearing it a few more times and see if she's willing to wear it at outside. Might see if there's any Halloween events coming up; could be a test run before seeing if she'll wear this to a con next year.
