Circa 1960s Ian Thomas Graphic Silk Dress with Original Belt

A bold and beautiful piece from Ian Thomas—private couturier to Queen Elizabeth II—this 1960s silk day dress is a masterclass in graphic modernism. The print is a vivid play of kinetic geometry, rendered in orange, saffron, ink, and white—evoking the optimistic, space-age pulse of the Swinging Sixties.

Tailored with precision, the silhouette skims the frame with softly gathered seams at the bust and waist for a subtly structured shape. It retains its original wide belt: a striking, interlaced design that draws the eye inward and anchors the movement of the print with a dramatic contrast.

Lined in fine ivory organza and finished with a hand-set back zip, the craftsmanship is quietly impeccable—true to Thomas’s couture background and royal commissions. Rare to find in this condition with original accessories intact.

Museum-grade British couture from a royal designer—an extraordinary piece of wearable history.
