* The brand: Well-known brands or those with a strong reputation for durability will often be more expensive.
* The material: Trousers made from durable, hard-wearing fabrics like polyester blends will usually cost more than those made from cheaper materials.
* The retailer: Department stores, specialist school uniform shops, and online retailers all have different pricing structures.
* The style: Plain trousers will generally be cheaper than those with extra features like pleats or specific designs.
* The size: Larger sizes may sometimes be slightly more expensive.
Therefore, it's impossible to give a single price. You could expect to pay anywhere from £10 to £40 or more per pair. To find out the actual cost, you should check the prices at the specific school uniform supplier recommended by your child's school or look at online retailers that sell school uniforms.
