There is nothing more eternal than custom made shirt. Wear it with a matching suit or jeans, or layer it with jumpers or dresses. Style for the office, a night out, or a special occasion. This workwear staple is a year-round staple—and it’s as versatile as a classic. In an effort to celebrate the humble button-down for all that it does, Zara has released its Icons Shirt Collection for a lesson on sewing shirts.
