For Natasja Sijthoff, turquoise is more than a color — it is a feeling. A memory of endless Mediterranean summers. As a young girl, she was mesmerized by the luminous turquoise waters of the Côte d’Azur and the soft pastel tones of the Riviera. That early enchantment became a lifelong source of inspiration.

Natasja is the daughter of Theo Sijthoff, the renowned “fashion king” of Rotterdam. For decades, he dressed virtually every major Dutch artist — as well as many international performers — and became widely known for his spectacular fashion shows and television appearances. Style, boldness, and showmanship were part of her everyday upbringing.

Growing up in this world of glamour and creativity, Natasja built her own career spanning more than forty years in the fashion industry. From the iconic Koetshuis at Oud-IJsselmonde in Rotterdam, she dressed national and international artists, blending personality with couture flair.

Today, she channels that experience, heritage, and craftsmanship into her brand ByNass Ibiza.

What began as Beautiful Pillows & Bags Made with Love has evolved into a complete lifestyle universe — including dresses, jewelry, pareos, perfume, and curated beach essentials.

Her collections are inspired by her travels to Ibiza, Bali, Southern France, and other sun-drenched destinations. Each piece carries turquoise hues, rich fabrics, and eclectic details — a tribute to the cultures and stories she encountered along the way.

The aesthetic is luxurious hippie-chic: effortless, feminine, and timeless.

At ByNass Ibiza, it is summer 365 days a year.

Surrounded by the beauty of Southern France, Natasja continues to create — guided by light, color, and freedom.
