Vintage 1920s One-Piece Bathing Suit Knitting Pattern (Fits 35–37″ Bust)

Recreate an authentic 1920s one-piece bathing costume with this simple, period-correct knitting
pattern. Originally worked in shrink-proof “Crocus” yarn (thickness not specified; typical of the
era it likely matches a 3-ply/fingering).

Size & Fit: Designed to fit a 35–37 inch bust (stretch depends on your gauge).

Materials & Tools
Yarn: Shrink-proof wool; modern 3-ply/fingering is a sensible substitute.
Needles: Old UK No. 10 (3.25 mm) and No. 12 (2.75 mm).

Gauge Note
As with all vintage patterns, swatch first to confirm tension before committing your materials.
Adjust needle size to achieve a firm, supportive fabric suitable for swimwear.

Perfect for vintage swimwear enthusiasts, historical costuming, and 1920s seaside re-creations.
