This button-up denim mini dress gives you a sharp, put-together look with its classic shirt-dress silhouette. The front button closure and belted waist create a defined shape, whilst the short sleeves and knee-length cut keep things casual and wearable.

Key Features
  • Front Button Closure: Easy to style open over a top or buttoned up for a neat, polished appearance that works with almost anything in your wardrobe.
  • Belted Waist: The adjustable belt defines your silhouette and gives you control over the fit, so you can wear it however feels best for your body.
  • Mini Length: A knee-grazing cut that's feminine and flattering, perfect for showing off your legs with trainers, boots, or sandals.
  • Casual to Smart: Layer it over a shirt for cooler days, or wear it alone with jewellery and sunglasses for an effortless, styled look that works from daytime outings to relaxed evening plans.
