We snuggled O+Kay cashmere sweaters and fell hard. Here’s how we rationalized the indulgence.1. Only the best for our bambinos. O+Kay sweaters are made of the highest quality twelve-gauge knit cashmere and are designed by Grace Sun, who has women’s wear cred.2. Prices starting at $50 are better than prices starting at $150.3. Simple cuts. V-neck vests, crewnecks, and cardigans never go out of style.4. As comfy as sweats but better looking.5. Buy a size up. Roll the sleeves and wear twice as long.6. We’ve never heard of anyone outgrowing a scarf — cashmere or otherwise.7. The mini lavender ruffle cape.8. Wear it every day. This fall, we’re replacing his ubiquitous fleece with a cashmere zip-up hoodie.9. Save money at the dry cleaner. Just handwash and lay flat to dry.10. Three words: hand. me. down.Available online at opluskay.com.30% off City Threads Our favorite way to layer it on this fall? City Threads.
