Die, Workwear!

Die, Workwear! started as Derek Guy's personal crusade against bad menswear advice and became the internet's most trusted voice on how men should actually dress. Guy, a former lawyer turned fashion critic, writes with the precision of someone who has spent years studying the difference between a properly constructed jacket and department store garbage. His Substack newsletter cuts through decades of marketing nonsense to explain why certain clothes work and others don't, grounding every argument in history, craftsmanship, and economic reality.

The newsletter operates on a simple premise: good taste isn't mysterious, it's learnable. Guy breaks down the construction details of a Savile Row suit, explains why Japanese denim costs what it does, and dissects the supply chains that separate luxury from theater. He writes about vintage Ivy League style) with the same analytical rigor he brings to contemporary streetwear. Every post reads like field notes from someone who has handled thousands of garments and remembers what each one taught him.

What sets Die, Workwear! apart is Guy's refusal to treat fashion as lifestyle content. He doesn't care about your personal brand or seasonal color palette. He cares about whether your tailor knows how to set a sleeve and whether you understand why certain fabrics age well while others disintegrate. His recommendations come with specific maker names, fabric weights, and price comparisons across decades. This is shopping advice for people who plan to own their clothes for twenty years.

The newsletter has become essential reading for anyone serious about menswear, from New York Times fashion critics to guys in Milan who thought they already knew everything. Guy's influence shows up in how other writers now discuss clothing, with more attention to construction details and less tolerance for marketing speak. He proved that talking intelligently about clothes doesn't require pretension. It requires homework.
