The Design
Celeste features a classic polka dot print set against a softly textured base fabric. The evenly spaced dots bring a timeless, playful feel, while the subtle crinkle in the cloth adds depth and movement, preventing the design from feeling flat or overly graphic.
The combination of print and texture creates a relaxed, lived-in look that feels easy to wear and visually interesting up close. It’s a versatile design that balances charm and simplicity, working effortlessly across everyday silhouettes.
The Fabric
Made from a soft cotton-rayon blend, this fabric is lightweight, breathable, and comfortable against the skin. The rayon adds fluidity and softness, while the cotton provides structure and durability, resulting in an easy drape that moves with the body.
The subtle crinkled texture is part of the fabric’s character, giving it a relaxed feel and making it forgiving to wear and travel with. Designed for comfort and everyday versatility, this fabric feels effortless while still offering considered detail.

Care Information
Seersucker is a lightweight, breathable fabric characterised by its softly puckered texture. The crinkled surface allows the fabric to sit slightly away from the body, promoting airflow and keeping it cool and comfortable to wear.
Naturally floaty and relaxed, seersucker drapes easily without clinging, making it ideal for warm weather and travel. Its textured finish gives garments a casual, effortless look while helping them hold their shape throughout the day.
This fabric is well loved for its easy-going nature. The puckered texture reduces the need for ironing and helps garments bounce back after wear, making seersucker a practical and stylish choice for everyday dressing.
Composition: 60% Cotton, 40% Rayon
