Step-by-step explanation:
When i was a little kid i had to make an last minute halloween costume for me and my sister i was about 9 so i took some hannah Montana Shirt and had a pink tutu and made a rockstar outfit and put some makeup on, and i made sister a Ballina outfit. I don't do halloween any more or wear costumes during any halloween or holiday. A Graduation Robe is not really a costume, but more of a achievement because you finished a high school, That wouldn't be a costume but a reward if anything.
