LONDON — Sophia Kokosalaki, a widely admired London-based clothing designer who drew on her Greek heritage in highlighting classical silhouettes and artful drapery, died on Sunday in London . She was 46.

Her death was confirmed by Antony Baker, her partner and the managing director of her brand, Sophia Kokosalaki. No cause was given.

Over more than two decades Ms. Kokosalaki became one of the most prominent Greek designers of her generation, respected by such star peers as Alexander McQueen and Kim Jones for her balancing a cutting-edge feminine look with ancient Greek, Minoan and Byzantine motifs.

She had earlier been a forerunner of a new wave of European fashion designers who moved to London to study, then stayed to set up their businesses .
