Each grade dresses up as a holiday that nobody ever really takes notice of…
Examples:
Labour Day -> people dress up as doctors, firemen, police etc.
Arbor Day -> people dress up in green/leafy outfits
Canada Day -> show your patriotism (red/white/maple leaves)
Mother/Fathers Day -> Dress up like old people
Victoria Day -> Dress like royalty
Be creative! There are tons!
