She is stout with a plump and round face, she has glossy black hair. As a Wise Woman she wears a very long red belt. She is younger than Reanne (who was 412 at the moments of her death), but older than the rest of the Kin in Caemlyn, including Kirstian who is known to be around three hundred and fifteen, so Sumeko presumably is more than 350 years old. This is confirmed by "The Wheel of Time Companion" where we find that she was born in 598 NE, so she is at least 401 when she first appears.
