Pinstripe trousers are one of those things men either get completely right or walk straight into disaster with. Worn as separates, they demand more thought than most men give them. Too heavy a stripe and you look like you’ve raided a costume rail. Too casual a pairing and the whole thing reads as confused. Get it right though and there are few things sharper. A clean white shirt, a plain knit, a well chosen loafer or brogue, and pinstripes stop being a suit component and start being a proper wardrobe move. We’ve been looking at cuts that work outside the boardroom without losing the authority the stripe carries, paying particular attention to fabric weight and how the trouser sits without a matching jacket to anchor it. Wool and wool blends hold the line here. Synthetic versions rarely do. These are the pinstripe trousers that reward the effort of styling them properly rather than punishing you for trying.
