Our story

Born from the stars

Sidera — Latin for stars — was born from a deep conviction: fashion should be as personal as your astrological chart. Each garment is a celestial artifact, designed to align the woman who wears it with her deepest identity.

Rooted in the language of astrology, femininity and ancient symbolism, Sidera is made for women who see fashion as an extension of who they are — and who they are becoming.

Blood oranges from Sicily, sun-bleached denim, night swims on an unknown beach, wilted jacaranda flowers, an overly generous Campari cocktail and a motorcycle ride along the coast in the dead of night.
