Idols who reached peak visuals with blonde hair? Doesn't have to be their "staple" hair color or a color they had for a long time, just your preference :) also feel free to include male idols, I just listed idols I know as a gg stan.
Blackpink Rosé- Her signature look that many fans have grown tired of, but it's iconicness is undeniable
Twice Dahyun- Usually it's thought the best combination is light skin-dark hair , but Dahyun proves that light skin-light hair is just as lovely
Red Velvet Yeri- In recent years Yeri's beauty has shone with light hair
Oh My Girl Jiho- As a blonde Jiho turned into a goddess
Gfriend Sowon- Sowon as a blonde became legendary after the 'Hush' stage
AOA Choa- finally to close out my post, we have the blonde bombshell of Korea, Park Choa.
