Add a Tie to the Billow Blouse by The Assembly Line

If you’re looking to adapt the Billow Blouse Sewing Pattern by The Assembly Line, this simple hack is a beautiful way to elevate the design and add a more refined finish.

The Billow Blouse is all about volume, with gathers at the rounded neckline created using elastic for a comfortable fit. The billowing raglan sleeves are finished with elasticated cuffs, giving the blouse its soft, relaxed silhouette.

Replace the Elastic Neckline with a Collar Tie

This free pattern extension from The Assembly Line allows you to replace the elastic neckline with a collar and tie detail.

The result is a more structured and versatile version of the blouse. The tie can be styled in different ways... wrap it once and tie a bold bow, or wrap it twice for a more understated necktie finish.

It’s a simple change, but one that transforms the overall look from relaxed to more polished, making it suitable for both everyday wear and more dressed-up outfits.

Why Try This Hack?

• Adds a more tailored, elevated finish
• Introduces multiple styling options with the tie detail
• A great way to revisit a pattern you already own
• Works beautifully in lightweight fabrics such as cotton lawn, voile or silk blends

What You'll Need

To make this version, you will need the original Billow Blouse sewing pattern by The Assembly Line, along with the free collar extension pattern pieces and instructions available from The Assembly Line Sewing Journal.

Please note: This is a free pattern extension, not a full sewing pattern, and is available as a digital download.

Sew the Look

For a soft, elegant version, choose lightweight fabrics that highlight the volume of the blouse and allow the tie detail to drape beautifully.
