My stakeholders come from various backgrounds and areas: cultural, class-based, ethnic, linguistic, and financial, leaving less space for a biased conclusion. The goal of this experiment is to determine what psychological effects are experienced when an individual changes their usual attire.

I have invited four interviewees for this experiment: a Russian, Greek, and Canadian male; and a Chinese female.

1. The Russian student, who would normally dress street casual (jeans and hoodies), was given a choice between formal clothing (suit and tie) and business casual. After a 4-week testing period, the subject picked business casual as the attire with the strongest positive impact on their behaviour, stating that it made him make more sound decisions in his daily life. 
2. The Canadian doctor would usually wear overalls with simple and conservative clothes, but he chose to wear street sportswear this time. He said that when he changed into sportswear after work, he felt very excited and became more outgoing and friendly, releasing his inner emotions.
3. The Chinese female chose a sexy vest and skirt as her new attire, contrasting against her usual conservative clothing. Out of protection, she hardly goes out at night, so she wants to see what nightlife culture is all about. The attire, alongside the atmosphere of the city, made her tap into her inner confidence and discover a part of herself that she never knew existed.
4. The Greek driver has little time for leisure, sometimes even going to work in his home clothes, having no time to dress up. He was saving money for his children’s tuition fees and hardly bought new clothes, so he took this opportunity and chose an expensive custom velvet three-piece suit. According to himself, wearing the suit helped in raising his self-esteem and sense of importance.

Based on the feedback they gave me, I conclude that an individual’s attire has significant influence on their mood, cognition, and sense of self. One weak point of the experiment is that an individual’s state of mind fluctuates day by day, meaning that the same attire can influence an individual in opposing ways depending on pre-existing conditions, such as their mood.
