The Women's Oversized Plaid Flannel Long Sleeve Button-Up Shirt is your go-to choice for effortless autumn layering. Cut in a relaxed oversized silhouette with a soft brushed finish, a classic collar, and a button-front placket, it's ideal for wearing open over a crop top or buttoned up on its own.

Why You'll Love It

  • Bold Check Pattern: A classic oversized plaid in eye-catching colourways gives this shirt a casual-cool energy that pairs effortlessly with denim shorts, jeans, or leggings.
  • Soft Brushed Finish: The lightweight brushed fabric delivers the warmth and texture of flannel without the weight or stiffness, keeping you comfortable all day long.
  • Versatile Long Sleeves: Wear the sleeves down for cooler mornings or roll them up casually for a relaxed, off-duty look — an easy, adaptable everyday piece.

Perfect For

Layer it open over a crop top and denim shorts for a weekend festival look, pair it with jeans and trainers for casual errands, button it up over leggings for a cosy autumn walk, or throw it on as a lightweight layer for a relaxed evening out.

Care Instructions

  • Machine wash cold on a gentle cycle.
  • Do not bleach.
  • Tumble dry low or lay flat to dry.
  • Cool iron if needed.
