Note that your check-in materials will be used as part of the judging process, thor costume adult so keep that in mind when putting them together. One change we’re making this year is that after your third check-in at 90% completion, our judges will select up to 50 of the strongest costumes to participate in an in-person judging session on the first full day of BlizzCon (Friday, November 1). You will be notified via email prior to BlizzCon if you are in consideration for additional judging, or if you’re being invited to participate in the Costume Exhibition.
