Drafting starts after purchase. This is not an instant download; no finished garment, fabric kit or printed pattern is included.

Planned triangle-cup design

Two softly shaped triangular cups meet a continuous elastic underbust band. A curved seam shapes each cup, while the cup bases attach directly to the elastic. The outline stays light, with no separate fabric cradle or underwires. Slim adjustable shoulder straps and a centre-back hook-and-eye closure complete the proposed construction.

The concept is intended for lingerie knit with suitable stretch and recovery, supported by a compatible lining. The pictured plum fabric illustrates the shape; a fabric color is not a separate pattern option. Stretch direction, elastic behavior and lining compatibility will need to be specified during preparation. Woven fabric and swimwear substitutions are not included automatically.

Construction and fit

The sewing plan focuses on joining the shaped cups, applying elastic without waviness, reinforcing strap attachments and finishing the back closure. Band tension and cup volume work together, so choosing by a cup letter alone is not sufficient. A fitting sample is essential before cutting your final fabric.

This design has not yet been drafted, sewn or fit-tested. The final size chart, finished measurements, material quantities, print layouts and PDF page counts will be confirmed when prepared. Contact Sewlore before ordering to confirm suitability. Custom fitting is not included.
