Essential White Straight Leg Denim Trousers | Denim | Castielli
White denim trousers cut to a straight leg with a high rise and flat front, holding a consistent width from hip to hem. This is the trouser that makes a navy knit look deliberate instead of default.
Why you'll reach for it
- Straight leg cut: one clean line from thigh to ankle, no taper games, no break issues over sneakers or loafers.
- High rise: sits at the natural waist, which keeps shirts tucked and the proportion long.
- Classic 5 pocket build: the familiar denim layout in a color that reads tailored.
- Belt loops: sized for standard belts, so the waist finishes properly.
Fit and fabric
Sized by waist from 29 to 36 in a firm denim weave that holds structure. True to size; the waist is precise, so measure your best fitting trousers before ordering. Expect minimal stretch, which is exactly what keeps the leg line clean.
Care
- Machine wash cold, inside out, with light colors only.
- Hang to dry to avoid heat shrink.
- Treat stains promptly; white denim forgives less than blue.

Care Instructions
Care Instructions
Wash cold on a gentle cycle and hang by the waistband to dry, so the pleat falls back into place. Cashmere and merino trousers go by hand or on the wool cycle and dry flat.

The Fabric
Natural fibres, chosen by season
Extra-fine merino and cashmere for the cold months. Every piece starts from the fibre that behaves best in its season, cut with room to move and finished to hold its line.
The Craft
Details you notice on the tenth wear
Reinforced seams and hems finished straight. Ribbing that springs back after a full day. The kind of detail you check after a season of wear, and it is still there.
