Effortless Poise, Thoughtful Layers

The Mariella Layered Wide-Leg Set brings understated elegance to every day, combining a fluid asymmetrical top with relaxed wide-leg trousers. Designed to fall softly over the figure without feeling restrictive, it offers a modern approach to polished dressing—no fuss required.

The top features soft layered panels and an open shoulder detail, gently skimming your frame for a refined, airy silhouette. The high-rise trousers flatter with a flowing, wide-leg cut and are finished with an elasticated waistband for easy wear.

Perfect for plans that run from day into evening, the Mariella set blends a refined look with versatile styling: team with simple jewellery for lunch or elevate with heels for a special dinner. Designed for true adaptability, it transitions seamlessly across your occasions and moods.

One considered piece, several real occasions—this set delivers on confidence, comfort and adaptable style every time you reach for it.

  • Elasticated high-rise waistband — Defines the waist and offers comfort for all-day wear
  • Relaxed, flowing fit — Movement-friendly silhouette that never feels restrictive
  • Day-to-evening versatility — Easy to dress up or down for multiple occasions
