This ribbed knit crew neck sweater is a versatile piece designed for everyday wear. The fabric features vertical ribbing throughout that creates visual texture and interest across the chest and body. It has a relaxed, comfortable fit with long sleeves and a rounded neckline that works well on different body types. The hem sits slightly longer than a standard crew neck sweater, giving you a modern, casual silhouette that pairs easily with jeans, trousers, or skirts.
Key Features
- Ribbed Knit Texture: The vertical ribbing adds depth and dimension to your look while the knit fabric keeps you warm without feeling heavy.
- Crew Neck Design: A classic rounded neckline that sits close to your neck and looks good with or without layering underneath.
- Long Sleeves: Full-length sleeves with ribbed cuffs that taper slightly, keeping your arms warm and creating a polished finish.
- Casual & Layerable: Works well as a standalone piece or layered under jackets and coats, making it practical for cooler weather and everyday casual outings.
We choose natural, hard-wearing fibers — wool, cashmere, cotton and suede — so each piece looks better with every season. The exact composition is listed in the description above.
Knitwear: hand wash cold or dry clean, lay flat to dry, store folded.
Coats & jackets: dry clean only; brush wool gently after wear and hang on a wide hanger.
Suede & leather: protect with a water-repellent spray and brush with a suede brush.
