Jalie - Paper Sewing Pattern - One-Piece Swimsuits

Jalie One-Piece Swimsuits

The Jalie 3350 One‑Piece Swimsuit Sewing Pattern is your go-to for versatile, stylish swimwear suitable for all ages. Choose between two design variations tailored to different tastes:

View A features a sweetheart neckline and contrast under-bust band that accentuates the bustline. It’s fully lined in front and has a chic open back secured with a clasp - perfect for fashion-forward makers.
View B offers a sophisticated twist-front bodice with a completely closed back for a clean, streamlined look.
Both styles are designed for four-way stretch swim fabrics like Lycra or spandex (60% minimum stretch horizontally and vertically), ensuring a snug fit and freedom of movement 

The front lining allows for the insertion of swim cups, adding optional bust support. Create a comfortable and polished fit by choosing between fixed or adjustable straps. With a pattern that encompasses 27 sizes, ranging from children's to women’s 2X (US size 22), you can make coordinated swimsuits for your family - ideal for matching sets or gifting.

The instructions offer clear guidance on sewing stretch swimwear, with detailed elastic placement and optional adjustable strap hardware. Jalie’s precise drafting ensures a flattering fit with features like princess seams, a defined underbust band (View A), and smooth twist detailing (View B) for confident swimwear that fits beautifully and lasts.
