Danielle “WhereisDanielle” Debs has made a name for herself with full scale Halo armor builds, solidifying her name in the global cosplaying community last year with the title of Cosplayer of the Year by the Australian Games Awards.

She began with no prior trained skills in crafting or sewing, and learned through trial and error, with a side of stubbornness.

Last year Danielle built five new full armour costumes, largest build to date is her Overwatch Brigitte costume, she documents her build process on Instagram and Twitch.
