There's a special note in the event's description about this issue: "Some issues have been found on-site regarding certain dress up outfits not showing for users. If this is happening to you, refreshing your browser's cache will fix this. On Windows, this is done by Ctrl + F5. Those on Mac will vary depending on the browser they use- with most, this can be found in the Settings menu."

(Thought it might be useful to include as it happened to me, and I realised it happened to a lot of people on the DC forums.)
