You see that there were only 3 sets of costumes left that look like they could be the clothes of the little girls that you heard of after reading their books for about 5 years of being a kid before turning 10 years old in Elementary School. You weren't exactly sure why the student council left you these sets at all.
The first outfit had a green dress with a white apron, white stockings, black slip-on heels, and a red cape with a hood attached with was the outfit for red riding hood. The second was a blue, and white dress covered in diamonds to symbolize Alice, and the final dress came with yellow hair extensions with a pink dress which symbolized the girl Goldilocks. You were having trouble choosing, so you rolled a 3 sided die with the same colors as the dresses to see which one you could wear.
