The Betty Oversize Sweater – A Cozy, Elegant Essential

The Betty Sweater is that go-to piece you’ll reach for all season long. With its oversized silhouette, clean lines, and cozy texture, it’s both timeless and modern. Designed for comfort and versatility, it’s perfect for layering over jeans or trousers, dressed up or down.

This sweater is knit flat in four pieces (front, back, and two sleeves) and then seamed. There is no shaping involved—just simple, meditative rows that let the yarn and silhouette shine. It’s an ideal pattern for intermediate knitters or confident beginners ready to level up.

Crafted in Andean Spirit and Andean Solid yarns by Sierra Yarns—a luxuriously soft blends of 60% baby alpaca and 40% Pima cotton—the finished garment feels like a hug. Lightweight, breathable, and warm without overheating, it’s a dream to wear.
