I wear a Calvin Klein pinstripe suit to my interviews. As long it's a subtle and wouldn't catch an awkward eye, then it'll pass by all eyes. Dress cool, sauve, formal, and conservatively - and that is enough to leave a favorable impression of yourself at the school. The chrome-plated blazer suit and annie glossy red shoes aren't exactly going to make you uniquely stand out positively. if I was an adcom, i'd totally be tempted to make fun of you 😛 .
