Product Insights
Le 31's Pleated Belted Pant Antwerp Fit - Straight & Loose is a travel-ready trouser with an integrated self-belt for on-the-fly waist adjustment during meals or travel, stitched-down pleats that create an elongating crease avoiding a carrot silhouette, and stretch fabric allowing movement without gaping. The recycled polyester-viscose-elastane blend holds pleat edges sharp while enabling motion, and the removable belt yields crisp or relaxed looks, coordinating with a matching jacket for a modern suit alternative. Tradeoffs: delicate cold wash and low-heat ironing are required to preserve stretch recovery and avoid baggy knees, and the 36-inch inseam needs hemming for low-profile shoes.
Verified claims
- Inseam
- Fixed 36-inch inseam for waist sizes 30-38.
- Waist adjustment
- Adjustable self-belt allows on-the-fly waist adjustment during travel or meals.
- Fit and movement
- Stretch fabric and pleats enable movement and a consistent straight-leg silhouette.
- Pleat performance
- Stitched-down pleats create an elongating crease, avoiding the dated carrot silhouette.
- Styling
- Removable belt yields two looks—crisp or relaxed—and coordinates with the matching jacket for a suit.
- Fabric
- Recycled polyester-viscose-elastane blend holds pleat edges sharp while allowing motion; machine wash with low-heat ironing refreshes the crease.
- Travel convenience
- Built-in belt eliminates need to pack a separate belt and allows on-the-fly tension adjustments.
- Silhouette
- Worn with matching jacket, creates a modern suit alternative with a relaxed silhouette.
- Comfort
- 3% elastane prevents pleats from gaping or pulling when sitting or moving
- Stretch care
- Stretch fabric requires delicate wash to maintain recovery and avoid baggy knees
- Belt
- Integrated belt allows on-the-fly waist adjustment for comfort after sitting or meals
- Stretch and fit
- Elastane stretch prevents pleat gaping and allows sitting and bending with less tension.
- Care and durability
- Cold machine wash and air drying preserve wet strength, stretch recovery, and pleats; recycled polyester gives wrinkle resistance and colorfastness.
- Care instructions
- Cold-water delicate wash, lay flat to dry, and low-heat iron with a press cloth preserve the trousers.
- Shoe compatibility
- Straight leg pairs cleanly with chunky loafers and sneakers, but 36-inch inseam requires hemming for low-profile shoes.
- Suit aesthetic
- Worn with the matching jacket, these trousers form an intentionally relaxed suit silhouette.
