Trending Now: Color-Pop Knits

Sweater weather has arrived, and it’s signaling a seasonal shift that has us rethinking our wardrobes. This year, we’re reaching for the softest cashmere and merino-wool knits to layer, but instead of the usual suspects of autumnal shades, we have our eye on more vibrant, rainbow hues usually reserved for the warmer months. On our editors’ radar are fire-truck red, shamrock green, cobalt blue and royal purple – four trending colors that will inject pigment and personality into your fall capsule. Read on to discover how to style them now…

A red knit has been the fashion set’s secret styling trick for several seasons, and there are no signs of this slowing down. It can give the most minimalist outfits maximum visibility, making it our go-to for an instant wardrobe update. To breathe new life into your fall outfits, consider pairing Tove’s bright-red ribbed sweater with Stouls’ leopard-print midi skirt, gold earrings and an oversized tote – it’s a look approved by NET-A-PORTER’s buying manager, Lydia Zacharis. Alternatively, simply drape the knit over your shoulders to add an attention-commanding flash of red.

A new shade is on the scene: a green knit is the enviably chic piece you need to add to your wardrobe. Worn tied around the waist of stylish celebrities like Daisy Edgar-Jones, a lime or shamrock-hued sweater adds an unexpected zing to dark indigo, black and cream. Try styling Lisa Yang’s inimitably soft cashmere style with your favorite fall essentials – think Nour Hammour’s brown-suede ‘Dalma’ jacket and Toteme’s ‘Classic Cut’ jeans – for a new-season outfit that’s easy to wear yet is anything but ordinary.

If you’re not already convinced by the vivid intensity of a cobalt-blue knit, now is the time to reconsider adding it to your rotation. This shade has been cropping up in countless collections of late, and fashion editors everywhere love it as a striking alternative to the aforementioned ‘pop of red’. We’d wear Guest In Residence’s ‘Cozy Crew’ cashmere sweater with Jil Sander’s mid-blue wash jeans and The Row’s chocolate-brown ‘Bamira’ coat to the NET-A-PORTER HQ, but it would really pack a punch with Carolina Herrera’s bright-red turtleneck layered underneath.

Seen all over the fall/winter 2026 runways, purple has emerged as this season’s dominant color trend. Designer and content creator Aimee Song showed us the power of the pigment when she stepped out in a striking purple knit knotted nonchalantly over one shoulder, proving that it’s undeniably eye-catching and pairs well with warm neutrals. Channel her look by sporting Loewe’s royal-purple wool sweater and Khaite’s camel-hued ‘Hunter’ straight-leg pants with Toteme’s sleek black leather mules – the pared-back pieces will really let the color sing.
