KEY DESIGN FEATURES
◆ One-piece swimsuit with a sporty silhouette
◆ Halter neckline with a narrow stand collar
◆ Centre-front Zipper for easy dressing & adjustable neckline opening
◆ Shaped front armholes that leave shoulders fully exposed
◆ Open upper back with straps
◆ High-cut leg openings
FIT NOTE
◆ Designed for a close, body-hugging swimwear fit
◆ Negative ease so the garment stays secure when wet
◆ Front Zipper allows some flexibility at neckline & bust
◆ High-cut legs visually lengthen leg line
◆ Open-back design gives extra freedom of movement through shoulders
◆ Choose size primarily by bust, waist & hip measurements; check torso length before cutting
CUSTOMISATION IDEAS
◆ Use a contrasting Zipper for a sporty feature
◆ Make Zipper invisible in a matching colour for a cleaner look
◆ Add swimwear lining to front or full garment for extra coverage & support
◆ Add removable bra cups if preferred
◆ Adjust leg opening slightly higher or lower to suit personal preference
◆ Use decorative topstitching or contrast thread to emphasise seam lines
SUITABLE MATERIALS
◆ 4-way stretch swimwear fabrics with good recovery
◆ Nylon/Lycra or polyester/elastane swimwear jersey
◆ Chlorine-resistant swimwear fabric for regular pool use
◆ UV-resistant performance swimwear fabric for outdoor swimming
◆ Matte, shiny or lightly textured stretch fabrics can all work well
Optional: lightweight stretch swimwear lining/power mesh for additional support
Avoid: fabrics with poor recovery or insufficient stretch, as they may become loose when wet.
AMOUNT REQUIRED:
* Size S: 65×90 cm / 26"×36"
* Size XL: 75×95 cm / 30"×38"
As always, it's impossible to give fabric amounts for every fabric type and every size. For clarity, I provide yardage for both the smallest and largest sizes, based on a suitable fabric width. To stay on the safe side, you may follow the largest cutting layout for any other size.
To find out the AMOUNT for a particular FABRIC in your size, you might like taking your pattern to the fabric shop – their assistants are always happy to help.
Otherwise, do it yourself:
- stretch a flat bed-sheet on a table or floor;
- fold it to the width of the material you plan to use;
- arrange ALL pattern pieces paying attention to the grainline desired-directions and seam allowances;
- measure the length you have got.
