Peggy Farrar is an Amritdhari Sikh who dons the turban and wears the 5ks.
Amritdhari Sikh is one who has received baptismal vows of the Khalsa initiated by Guru Gobind Singh and he/she abides by these vows and follows the 'Panj Karari Rahit' (rules of wearing the 5ks), the distinctive insignia introduced by the Guru comprising five symbols, each beginning with the letter K. These are Kesh (long unshorn hair and in case of men, beard too), Kangha (a comb to keep this hair tidy), Kirpan (a sword), a Kada (a wrist band) and a Kaccha (an undergarment).
