School Trousers, Skirts and Pinafores as a Bulk Bottoms Programme

Tops get the design attention in a school range, but bottoms generate the fit complaints. Waists that will not adjust, lengths that will not let down, pleats that collapse by half-term — these are the problems a bottoms programme is built to prevent. They are also the garments with the longest size conversations, because a trouser either fits at the waist and the hem at once or it does not fit at all, and the grey or navy below the waist is what makes a group of children look uniformed from a distance.

Why bottoms are bought as a programme

Trousers, skirts and pinafores share everything that matters: the cloth, the colour, the waistband policy and the size run. Buying them as one programme means a skirt and a trouser in the same size actually fit the same child, and the grey of one is the grey of the other. It also means the size curve is planned once, across all three garment types, from real sales data where you have it — rather than guessed garment by garment.

Waistbands, pleats and hems

The adjustable inner waistband — elastic and buttons inside the waist — is the single most valuable construction feature in children’s bottoms: it extends each size’s fit range and reduces the sizes a shop must stock. Pleats are heat-set and topstitched so they survive the wash instead of being pressed into memory. Hems carry an allowance so length can be let down as children grow. How the size structure beneath all this is set is covered under grading.

One cloth across the range

Washable polyester gabardine is the default: it keeps a crease, resists abrasion and survives hot domestic washing. Polycotton twill serves where a softer hand feel is wanted. Whichever is chosen, all bottoms in the range are cut from it, so colour and behaviour stay identical across garment types — and across re-orders, because the cloth standard is retained on file.

Getting the size curve right

Send last season’s sales by size if you have them, or the pupil roll by age if you do not. The cut plan is built from that evidence, and each re-order sharpens it further.
