I'm a recent college graduate about to embark on a new career in advertising. I've always liked to look good, but now my job requires a suit every day and my wardrobe simply isn't equipped. For suits, I have one wool dark navy chalk-stripe suit (3-button, double vented) and a grey flannel (c'mon, this is advertising) glen-plaid 3-button. If it matters, I live in the northeast. So here's my request: What is the minimum number of suits I need, and more importantly, what should they look like? What colors, materials and styles? I'm pretty comfortable with my knowledge of manufacturers so I'm less interested in that kind of recommendation, but if there is a certain maker you think every man needs (i.e. "No discerning gentleman should be without at least one Oxxford suit..." etc. etc.), I'm all ears. A list followed by insightful comments would be most useful. Please help a young professional on the path to sartorial enlightenment.
