Thayer Jacket Pattern Sizes 14-30

A great jacket earns its place in your wardrobe. The Thayer Jacket by Grainline Studio is designed to do exactly that.

Inspired by classic workwear but refined with thoughtful tailoring details, Thayer is a stylish, fully lined jacket that combines practicality, comfort and timeless design. Its gently shaped A-line silhouette offers a flattering fit while still allowing plenty of room for layering through the cooler months.

Whether you're heading out on a crisp autumn morning, running errands around town or enjoying a weekend getaway, the Thayer Jacket is the kind of handmade garment you'll find yourself reaching for again and again.

Beautiful design details elevate this pattern well beyond a basic coat. Front princess seams create flattering shaping through the bust and torso, while two-piece sleeves provide a professional finish and comfortable movement. Functional patch pockets are paired with hidden in-seam yoke pockets, giving you plenty of storage without sacrificing style.
