Ikele is a single stiff string or circlet of coral beads. It is worn by chiefs, such as senior chiefs who have been made Enigie (Inneh 2007, p.107), and is a sign of nobility and rank. The Ikele may only be worn once the Ọba has conferred a person with the right to wear the beads, and the Ikele must always be worn when appearing before the Ọba. According to Ekhaguosa Aisien (in Plankensteiner 2007, cat. nr. 301, p.512) when a chief is wearing the Ikele, they may not eat nor drink in public, and they “constitute an embassy of the Benin Palace wherever he might be.”

The Ukpẹ ọkhọkhọ is a distinctive hairstyle and coral-beaded headdress worn by the Iy’Ọba. The headdress includes a projection called the ‘ede Iy’Ọba’, which indicates that “her spiritual potentialities are closer in quality to those of her ruling son than they are to the powers of the nobles” (Aigbe Eson and Ihama Iguneronmwon in Blackmun 1991, p. 60). The Iy’Ọba’s hairstyle and headdress are meant to resemble ukpe-okhue, or the curved parrot’s beak (Kaplan 1993).

Barbara Blackmun (1991, p. 60) argued that “Benin art is multivocal, and any depiction of the Iye Ọba [sic] is a reference to Idia. Every woman who holds the office of lye Ọba plays the part of Idia, the ideal model of an Ọba’s mother.” Wearing the Ukpẹ ọkhọkhọ is one of the ways the Iy’Ọba plays the role of Idia.

The Ukpan obọ eva (coral-bead crossed baldrics) were worn as part of the ehaingbehia, the full ceremonial regalia, by only high-ranking members of the palace, including the Ọba himself, the Iy’Ọba, the Edaiken, and the Ezọmọ (Ben-Amos 1999, pp. 68, 141; Osadolor in Plankensteiner 2007, cat. no. 70, pp. 322–323).

Ẹguẹn are worn by the Ọba and chiefs as part of their Ehaengbehia, the full regalia worn during special ceremonies. Ẹguẹn are worn around the ankles or calves and can be made from beads, ivory, brass or even iron. A separate category, called Elubase, refers to those which have integrated rattles or crotal bell attachments, however both are described as anklets in English.

As early as 1899, Read and Dalton commented that the anklets worn by figures shown on plaques were a signifier of high rank. Today, anklets continue to signify social status, with the Ọba wearing many ivory and coral anklets stretching up his calves as part of his ceremonial regalia (Okpokunu, Agbontaen‐Eghafona & Ojo, 2005, p.162[106]). However, anklets were not the preserve of the Ọba alone, and different kinds and quantities were worn by other members of the royal court and Edo people. For example, Flora Kaplan (2006, p.85[107]) described a photograph of Iy’Ọba Aghahowa N’Errua, who took her title in 1981, in which she wears coral anklets as one of a number of insignia of her newly invested high rank. In contrast, brass anklets would be worn by young male attendants to the Ọba (see attendant figure), such as sword bearers or Emada pages (Kaplan, 2006, p.90[107]).

In the 16th century, Ọba Ẹsigie established the title of Iy'Ọba (Queen Mother) in honour of his mother, Iy'Ọba Idia, for the crucial role she played in the Benin–Idah War (1515–16). She is often described as “the only woman who went to war” ( ).

The Iy'Ọba can usually be identified by her distinctive curved, conical hairstyle, known as Ukpẹ ọkhọkhọ, which is said to have been introduced by Iy'Ọba Idia (Kaplan 1993, p. 58). In addition, the Iy'Ọba was permitted to wear certain items of attire otherwise reserved for the Ọba, such as the Ewu ivie (coral-beaded shirt) and Ukpan obọ eva (crossed coral-beaded baldrics), as well as regalia associated with senior chiefs, including the Odigba (coral-beaded collar) and Udahae (coral-beaded forehead band) ( ).

Representations of the Iy'Ọba appear on ivory Emwin Arhe (royal treasures), including the five famous Uhunmwu-Ẹkuẹ (pendant masks) believed to depict Iy'Ọba Idia, as well as on a number of Aken'ni Elao (carved altar tusks). She is also represented in brass and bronze, including on Ikẹgobọ (altars to the hand) and Urhotọ (altar tableaux) made for Iy'Ọba shrines and altars ( ). In these representations, the Iy'Ọba is often accompanied by female attendants who form part of her retinue.
