Here are the transmog outfit creations from Elfpack's World of Warcraft members.
To add your own outfits, take a high-quality screenshot of the full outfit, upload the image (you can upload it straight to Elfpack, see Uploading Images), edit the wiki-page and add it below the others. Beside it, include your Elfpack username and a list of the main items used. If you want to share your screenshots, go to World of Warcraft Screenshots instead. If you're new to editing wikis, simply make a comment and somebody will help you out!
