Discover Timeless Blue Knit Sweaters for Women That Look as Good as They Feel at Aran

There’s something about a blue knit sweater. It’s coastal, calming, and endlessly wearable. Whether it’s a navy or light blue knit sweater, it feels grounded and graceful. They pair wonderfully with denim, neutrals, or layered over whites for a timeless look you can always fall back on.

Aran Sweater Market is the world’s leading source for authentic Irish sweaters for women, carrying on a heritage that’s three centuries in the making. 

Everything in our catalogue is knit using traditional Aran stitches, each telling its own story. From the protective Cable stitch to the wish-for-luck Honeycomb, these patterns connect you to the land, the sea, and the generations who came before.

Frequently Asked Questions

What shade of blue is the most versatile for everyday wear?

Navy - it works with everything from jeans to dress trousers. Lighter blues like denim or sky bring a softer, more relaxed tone to your wardrobe for spring and casual layering. There’s something for every taste here at Aran.

Will this blue sweater fade or lose its colour over time?

No. Our blue sweaters are dyed using high-quality, long-lasting methods and knit from resilient natural wool. They’ll look as good a few years from now as the day they arrived if you care for them correctly. 

How do I choose the right size or fit?

Our sweaters have a natural stretch and tend to relax slightly with wear. Choose your usual size for a relaxed fit, or size down for a neater silhouette or for layering under jackets. Always refer to the size guide on the product page, as each material will drape a bit differently. 

Are these knit sweaters itchy?

No. Our wool sweaters for women are ultra-soft since we use merino wool, which is much smoother than traditional wool. You might still consider wearing a thin cotton layer underneath if you have sensitive skin, though.

Are there special care guidelines for Aran sweaters?

You need to treat your new sweater like the heirloom it is. We recommend gentle handwashing in cold water with mild wool detergent, then lay it flat to dry. Machine washing or tumble drying can damage the natural fibres.
