BPink had a combination of factors that allowed it to get very popular internationally:
- concept that appeals to westerners
- music that's familiar/agreeable to westerners ears
- some members with personalities that westerners are perceptive to
- luxury fashion aura
- 3/4 members speak english very well
- visually Lisa was racially ambiguous which appeals to westerners
- overall the group had a more "global" feel than a Korean feel
GIDLE could have been a potential candidate but with the ethnic hip incident and they aren't Big 3, not really. They suit pan-Asian vibes more. I really don't see another girl group being able to achieve what BPink did in the west. Unless YG, TBL or HYBE have something else planned with similar high appeal to westerners.
