Girl group Pritz is coming under fire for wearing armbands that some say are noticeably similar to the ones Nazis wore during World War II.

Rookie girl group Pritz is in the middle of a controversy over an outfit choice. The Wall Street Journal reported on Twitter users noticing that Pritz’s four members wore black outfits with red arm bands. The arm bands had a white circle in the middle, with a black x-shaped design, and look eerily like the Nazi swastika armbands.

Twitter users also said that it looked similar to armbands used by Hungary’s Arrow Cross Party, a party that promoted racial purity and ruled Hungary in 1944, during World War II. Its leaders were tried as war criminals by the Soviet Union following the end of World War II.

Pandagram, Pritz’ entertainment agency, said that the “thought never occurred” that it the armbands and black outfits could be reminiscent of Nazi uniforms.

According to Pandagram, the logo was inspired by traffic signs, with black numbers written on white circles surrounded by red. The X-shape has arrowheads at the end to symbolize Pritz’ ambitions of expanding “without a limit in four directions,” according to Pandagram’s representative.

The girl group wore the armband outfits on November 2, but sang the same song at an event on October 25 without the armbands.

Pandagram is deciding whether to change the symbols, according to reports.

Korean commenters online wondered whether this was public relations stunt to get publicity for the rookie group. There was also worry that Western K-Pop fans would be offended by the armbands that recall World War II and the fascist Nazi government.

Pritz debuted in April 2014 with an anime-themed song, “Go Girls!” The group is modeled after Japanese idol groups and has four members, Hana, Yuna, Ari, and Shua. Pritz is making a comeback this November.
