This women's oversized button-down long sleeve dress is your go-to choice for effortless everyday style and relaxed comfort. Featuring a classic collared neckline, full button-down front, and subtle side slits, it suits women who appreciate a timeless, easy-wearing silhouette that moves with them throughout the day.

Why You'll Love It

  • Relaxed Oversized Fit: The intentionally roomy silhouette drapes beautifully and flatters a wide range of body shapes.
  • Thoughtful Side Slits: Subtle hem slits add ease of movement and give the maxi length a graceful, flowing finish.
  • Versatile Button-Down Front: The full button closure and shirt collar create a smart-casual look that works dressed up or down.

Perfect For

Pair with sandals and a straw bag for a relaxed weekend brunch, or wear with heeled mules for a smart-casual dinner. It works equally well on a city break or holiday, and layers neatly over a slim-fit roll-neck in cooler months. Available in sizes XS to 2XL.

Care Instructions

  • Machine wash cold on a gentle cycle.
  • Do not bleach.
  • Tumble dry low or hang to dry naturally.
  • Cool iron if needed, avoiding buttons.
