Its gonna be quite short as I actually don't remember most of it. (My memory isn't the best)
So, it was 6-7years ago, I went above and beyond for that one Halloween, and made a full Pyramid head costume. Scared the hell of my lil brother (full on tears running towards mum scare), but he loved it (after I took my "Head Pyramid). Skip a few years after and he still remembers it! and he brags about it to his friends of his big sister being this amazing horror cosplayer.
But in reality, I looked back at the photos, and It looks like I am wearing a bleaming cardboard box in a shape of a wonky pyramid and hold by duct tape, painted with golden glitter (it was so shiny XD)
Till this days, I always say to everyone how awesome that costume was and hide any evidence, they'll just have to believe my word...
