17 Best Coastal‑Grandma Cardigans to Shop for Spring 2026

Most spring fashion trends are quite predictable, like florals, pastels and light-weight knits. But this season has a couple of surprises up its sleeve. Coastal‑grandma cardigans are majorly in, and we’re leaning into the soft, seaside‑inspired vibe. Though it first popped up around 2022, this social‑media‑famous trend pays tribute to the linen‑loving, beach‑walking women who embody quiet coastal luxury. We’re talking Nancy Meyers–style icons like Meryl Streep and the late Diane Keaton — women who make coastal-inspired fashion look youthful and stylish, not frumpy and forgettable.

In honor of this cozy-chic aesthetic, we’ve rounded up 17 coastal‑grandma cardigans that capture the breezy charm, soft textures and simple elegance the look is understood for. From puff‑sleeve silhouettes to colourful and open‑stitch styles, these picks from Amazon, Nordstrom, Macy’s and Abercrombie & Fitch make coastal luxury feel totally wearable. Shop the look below — starting at $17.
