White shirt and beige pleats under a navy soft jacket

4 piecesRelaxedTransitional

Why it works

White clarifies the open collar inside navy, while beige and brown create a warm lower half. Pleats add shape without demanding a narrow trouser fit. The unstructured-looking outer layer reads as a separate jacket rather than part of a matching suit, giving the outfit a defined business-casual direction where an open collar is appropriate. Use white open-collar shirt to give the upper center a clear collar and placket while leaving the surrounding pieces relatively quiet. Use beige pleated trousers to add shape at the waist while keeping enough ease for a clear relaxed fall. Use navy unstructured jacket to create a tailored-looking outside frame without requiring the inner pieces to become narrow. Use brown plain-toe derbies to add a defined endpoint that can support both straight trousers and a more textured upper layer.

The proportions

Get the fit right.

The shirt collar should sit inside the lapels without spreading over them. A tidy tuck needs enough ease to sit and raise your arms. Let the pleats remain mostly closed when standing, and keep the jacket long enough to cover the waistband without swallowing the upper thigh. Show some of the derby lacing below a restrained hem break. Check the complete combination while seated and moving normally, with the actual footwear you intend to use. A clear illustrated proportion is a starting point, not a substitute for comfort or real garment measurements.

Your wardrobe, your version

Make it yours.

Choose flat-front beige trousers for a quieter waistband while preserving the bright shirt center and dark navy outer edge.
Use pale blue instead of white for less central contrast, keeping the brown footwear plain so the adjustment remains subtle.
Remove the jacket for a simple daytime version and check that the shirt tuck and fit still give the light trousers a clear upper boundary.
