Black jeans are one of the most reliable items in a boy's wardrobe, and this narrow leg cut from Childsplay is built to justify the space they take up. Made in Turkey from a 97% cotton, 3% elastane denim, the fabric has just enough stretch to move comfortably without losing the clean, structured silhouette that makes narrow leg jeans worth choosing over a more relaxed fit. The result sits somewhere between a traditional straight leg and a skinny jean — tailored enough to look considered, but not so fitted that it restricts movement.

Black denim is one of the easier tones to dress across occasions. It pairs cleanly with the corduroy shirts in this range, works under a casual hoodie for school, and holds its own next to a smarter jacket for family events or celebrations. Unlike mid-wash or light-wash denim, black doesn't show light scuffs and surface wear as readily, which makes it a practical choice for regular use.

Wash at 30°C or below and turn inside out to protect the black dye — this is the single most effective step for keeping black denim looking dark rather than greying out over time. Avoid tumble drying on high heat, which can cause the elastane to break down and the fabric to shrink at the waist and leg.
