Rebecca Page Children's Posy Pleated Pants Sewing Pattern – Downloadable PDF

The Rebecca Page Posy Pleated Pants pattern is a beautifully detailed children's sewing pattern that produces a pair of elegant, structured pleated trousers sized from Newborn through 12 Years. Designed by Rebecca Page and available as a downloadable PDF, this pattern is rated advanced in difficulty, making it an excellent project for experienced home sewists who want to create a polished, tailored garment for children. The finished pants feature classic design elements rarely seen in children's clothing, including inverted box pleats, back darts, an optional sash with sash loops, optional side pockets, and a neat waistband finish.

What You Will Make

The Posy Pleated Pants are structured children's trousers with a tailored silhouette. The front of the pants features inverted box pleats, which add volume and a sophisticated drape to the front panel. The back is shaped with darts for a fitted, contoured finish. The waistband is fully constructed and neatly finished, giving the garment a ready-to-wear appearance. An optional sash and coordinating sash loops can be added for a decorative belt-style detail that elevates the design further. Optional side pockets add both practicality and style. The pants are finished with a clean hem at the leg openings.

Techniques Used

• Back dart construction – shaping the back seat of the trousers for a tailored, fitted look
• Inverted box pleat formation – creating structured front pleats that are a hallmark of classic tailored trousers
• Side seam construction – joining front and back trouser panels cleanly
• Optional pocket insertion – adding functional side pockets within the side seams
• Front and back rise seaming – constructing the crotch curve for a comfortable, well-fitted seat
• Inseam sewing – joining the inner leg seams to complete the trouser shape
• Waistband attachment and finishing – applying a structured waistband with a neat, professional finish
• Optional sash construction – making a fabric belt or tie to complement the pants
• Optional sash loop attachment – adding fabric loops to the waistband to hold the sash in place
• Hemming – finishing the leg openings neatly

Stitches and Sewing Methods

As a sewing pattern, the Posy Pleated Pants are constructed using standard sewing machine stitches and techniques appropriate for woven or structured fabrics. Key sewing methods include:

• Straight stitch – the primary stitch used throughout for seams, darts, pleats, waistband, and hem
• Dart stitching – precise tapered stitching to create the back darts
• Topstitching – likely used to secure waistband and other structural elements neatly
• Seam finishing – recommended to prevent fraying on woven fabrics, using a serger, zigzag stitch, or similar method
• Pleat pressing and stitching – careful pressing and stitching to form and hold the inverted box pleats in place

Materials and Tools

The pattern includes a dedicated Materials & Tools section with specific requirements. As a structured trouser pattern rated advanced, the Posy Pleated Pants are best suited to woven fabrics with body and drape, such as cotton twill, linen, chambray, ponte, or similar suiting-weight fabrics that will hold the pleat and dart shaping well. Fabric requirements vary by size across the Newborn to 12 Years size range. Additional materials typically required for a project of this type include:

• Woven fabric – main fabric for the trouser body, waistband
