Pristin 프리스틴, formerly known as Pledis Girlz, is a female idol group formed by Pledis Entertainment in 2016.
Several members of the group appeared on the television show "Produce 101." As the prize for becoming two of the top contestants, members Nayoung and Kyulkyung went on to debut as part of the project girl group I.O.I. Pristin is composed of ten members: Nayoung, Roa, Yuha, Eunwoo, Rena, Kyulkyung, Yehana, Sungyeon, Xiyeon, and Kyla.
The group debuted on March 21, 2017, with their first EP Hi! Pristin.
In 2010, Xiyeon appeared in After School's "Bang!" music video. Previously, she'd starred in several commercials and dramas as a child actress.
In 2013, some of the members performed alongside their label mates Seventeen during their Like Seventeen concerts. Nayoung also made appearances in a number of music videos, including Kye Bumzu's "Game Over," Troy's "Why Are We," and Hanhae's "Man of the Year." All of Pristin appeared as backup dancers in Orange Caramel's music video for their 2014 single "My Copycat."
In 2015, Eunwoo, Rena and Kyulkyung appeared in Seventeen's music video for "Mansae." Prior to joining Pledis Entertainment, Eunwoo had been a contestant on the television shows "Superstar K4" and "The Voice Kids." Rena also participated in the fourth season of "Show Me the Money," but was eliminated during the second round, "1 Minute Rap."
Nayoung, Roa, Yuha, Eunwoo, Rena, Kyulkyung, and Xiyeon competed in the Mnet survival television program "Produce 101," which aired from January 22 to April 1, 2016. While five of the members were eliminated, Nayoung and Kyulkyung became part of the final lineup for the project girl group I.O.I., which made its debut on May 4 with the single "Dream Girls."
Yehana served as a backup dancer during Seventeen's concert in February 2016.
Pledis Entertainment announced their pre-debut team, Pledis Girlz, on March 23, 2016. Eunwoo was featured on a single by Seventeen's Vernon titled "Sickness," part of the soundtrack for the webtoon "Love Revolution," on March 23. They held concerts from May 14-September 10, 2016, with the members performing weekly, with the exception of Nayoung and Kyulkyung who were promoting with I.O.I.
They released the digital single "We" on June 27, 2016. It was composed by Eunwoo and Sungyeon and written by Roa, Eunwoo, Sungyeon, and Xiyeon.
In July 2016, Sungyeon became a contestant on JTBC's singing competition "Girl Spirit."
They held their last concert as Pledis Girlz, "Bye & Hi," on January 6, 2017, and announced their official group name to be Pristin, a portmanteau of "prismatic (bright and clear)" and "elastin (flawless strength)."
On March 2, Pledis Entertainment released a teaser through the group's social media platforms and confirmed their debut as March 21.
On March 21, Pristin officially debuted and released their first EP Hi! Pristin with their lead song "Wee Woo."
