how to dress up for Halloween for students at the university of yale?

the outcome must demonstrate an awareness of how language and meaning are shaped by culture and context. the unit topic is language and communities(nation/region). the format must be a power point. the presentation slides must show main words in bullet points and pictures of Halloween costumes. It has to be like a dress code for Halloween costumes for the students in the university of Yale. the main purpose is to show and inform students about appropriate costumes for Halloween and not dressing up to represent cultural or a religious costume. also i want you to tell me what to say for each slide in full sentences as if i am going to present in a note card. The slides can not show full sentences it has to be 4 to 6 bullet point of the main words.
