The "girl group" members in question are none other than the 4 WINNER members, who were spotted wearing bright, neon pink wigs during a fansign event!

Netizens divided up the members by what they would be in charge of after "debuting", such as the member who is kind to kids as well as the only member sporting a two-tone hair style (aka Kang Seung Yoon):

The member in charge of rap (aka Song Min Ho): 

The visual member (aka Kim Jin Woo):

And the femme-fatale member whom all the men will keel over (aka Lee Seung Hoon):

Netizens comments included, "Hey two-tone, isn't your wig on way too carelessly kekekeke", "My Neon Pink bias is Lee Seung Ha unnie! Please walk the flower road!", "Neon Pink kekekeke", and more, but some also found it, "Not funny".
