Our Year 12 house was called "Bunnings Warehouse", so everyone dressed up as some kind of construction worker, wearing fluoro vests, some had the "bogan" look lol, some tried to look cute with inflatable hammers etc. And EVERYONE wore plastic yellow "hard hats", mostly bought from Hot Dollar lol. One of my friends dressed up as a wall painter, that looked cool.
I wore a hard hat too, except I tied my hair back and wore a black suit accompanied by a business tag saying
"Warehouse
We'll beat you by 10%
