What you’ll make
Sew the Will swim trunks, a lined shorts-style swimsuit with side pockets and an elastic waistband.
Eyelets and a drawstring provide extra adjustment at the waist. The design is suited to swimming and comfortable warm-weather wear.
What you’ll learn in this class
- Cut mirrored pieces and identify the front and back.
- Finish lining edges with fold-over elastic.
- Build the side pockets without closing their openings.
- Assemble the rise, inseam and side seams.
- Install eyelets or make buttonholes for the drawstring.
- Attach the waistband and lining while leaving access for the elastic.
- Insert elastic and a drawstring, then finish the leg hems.
Fabric and notions
The demonstrated outer fabric is Tactel, paired with an interior lining and mesh pocket bags. The project also uses waistband elastic, fold-over elastic and a drawstring.
A stretch or super-stretch needle is used in the class. Choose stitches and seam finishes suited to the stretch in your fabrics.
Make it your own
Lengthen the pattern for a Bermuda-style leg or shorten it for briefer trunks. Account for the 3 cm hem allowance when changing the finished length.
Eyelets are optional. Machine-sewn buttonholes can provide openings for the drawstring instead.
Pair the trunks with the basic men’s T-shirt, using matching fabric for its pocket. See how to assemble a PDF sewing pattern.
Sizing
The pattern covers sizes 36/38 through 52/54. The chart spans waist measurements of 70–110 cm and hip measurements of 82–122 cm.
Use both waist and hip measurements when choosing a size. The pattern also provides size-specific elastic and drawstring lengths.
The video class includes A4 and A0 patterns plus a project-information PDF with measurements and material guidance.
