This belted maxi dress combines elegance with everyday wearability. The long sleeves and keyhole neckline create a refined look that works for formal events and smart occasions. A decorative belt cinches the waist, giving shape to the flowing skirt that falls to the ankle. The dress has a wrap-style bodice that's easy to wear and flattering across different body types. You can dress it up with heels and jewellery or keep it relaxed with white boots, as shown here.

Key Features

  • Keyhole Neckline: A cut-out detail at the centre front adds visual interest and breaks up the formality of the dress without feeling too casual.
  • Belted Waist: The decorative belt pulls everything in at the centre and lets you adjust the fit to suit your shape, making the dress work for different sizes.
  • Long Sleeves: Full-length sleeves with gathered cuffs keep you warm and give the dress a more polished, put-together feel.
  • Wedding Guest Ready: The maxi length, structured belt, and modest neckline make this dress ideal for weddings, formal dinners, and special celebrations where you want to look smart without overdoing it.
