I'm a teacher trying to build an interchangeable wardrobe. I own a pair of black, charcoal grey, brownish grey, dark blue, and dark blue pin stripe wool trousers, two pairs of polyester-rayon blend black trousers, and one pair of khakis. I plan on purchasing black oxfords like park avenues and pairing them with pants above. I rarely wear suits, but I've read that everyman should own black oxford lace-ups. I own the following which I have already worn. Kenneth Cole Reaction Shoes, Key Note Moc Toe Loafers I purchased the following unworn shoes. I have over spent, and need to budget for slim fitted khakis and button-up or v-neck shirts. If I could only keep one pair which would you suggest? Two pairs?
