The dress that makes strangers stop and ask: "Where did you get that?"

Mia is designed for women who want to look effortlessly put-together without spending an hour getting dressed. The mix of horizontal and diagonal stripes creates a visually elongating effect that flatters the silhouette naturally, while the flowing A-line skirt moves beautifully with every step.

Elegant enough for a dinner out. Relaxed enough for a Sunday afternoon. And yes — it has pockets. Real ones.

Why you'll love Mia

  • Flattering stripe pattern that visually elongates and slims the silhouette naturally.
  • Elegant boat neckline that frames the shoulders and gives a polished, timeless finish.
  • Deep side pockets — practical, discreet, and without compromising the shape.
  • Flowing A-line skirt with a graceful drape that moves beautifully with you throughout the day.
  • Available in Red, Blue & Black — a colour for every mood and every wardrobe.
  • Fits sizes S through 3XL — designed to flatter every body.
