Uniqlo Linen Shirt

Uniqlo is a great place to start if you're building a work wardrobe on the cheap – if the fit works for you. For guys who are slim, it's perfect, but guys who aren't will have to go up a size and then spend money to tailor the sleeves. Still, its offerings are by and large worth the effort. Uniqlo divides its button-downs into "Casual" and "Dress" shirts, but don't pay attention to that: The casual linen line comes in the best colors and looks by far the most expensive. For days when you want to blend in at the office, pick something solid in a dark color – the 09 Black, 07 Gray and 67 Blue are fantastic – or, when you want to make more of a statement, go for the linen stripe in 10 Pink, 03 Gray or 64 Blue.
