Plus-Size T-Shirt Dresses

Our plus-size T-shirt dresses make excellent all-rounders for casual days. Discover easy throw-on styles made from soft fabrics like cotton and jersey fabrics, for a breathable and lightweight feel plus a flattering drape. Choose from relaxed, oversized fits to more structured silhouettes that create a more feminine appearance. We’ve got options from popular brands like Seasalt Cornwall and Albaray – or try our own-brand options by M&S Collection. Our ladies’ plus-size T-shirt dresses are part of our wider plus-size clothing edit, which includes womenswear in sizes up to 24 and 26. If you’re looking to switch up your shape, try one of our structured plus-size shirt dresses, or embrace a more flowing fit with our plus-size swing dresses, made with breathable fabrics and gorgeous prints.

What style of plus-size T-shirt dress are you picturing? Keep things simple with clean, block colours or opt for stripes, prints and subtle detailing to add a little flair. Details like shirring, side pockets and leg splits further enhance the wearing experience. Our wider plus-size edit is brimming with pieces for pairing with your T-shirt dress – pick out wear-with-anything items from among our black plus-size clothing, or brighten things up with fresh white plus-size clothing.

Want to add a little texture? Try introducing pieces from our suede plus-size clothing or embroidered plus-size clothing edit – a jacket or accessories can instantly elevate a casual outfit. When the temperature drops, layer with cosy knits from our wool plus-size clothing collection, perfect for transitional dressing.
