aespa's Winter has caused quite a stir with her striking long hair.

On an online forum, netizens are actively discussing her latest appearance in a range of backstage rehearsal photos taken before aespa's live performance at the Yeongdong Daero K-pop Concert on October 8. In the photos, Winter adorns what the netizens are describing as 'beautifully long, wavy red hair extensions,' cascading in the wind against an outdoor backdrop.

Previously, netizens have remarked that they have trouble deciding whether Winter looks better with long hair or short hair. After seeing these snapshots, however, one uploader of the forum post confessed that they have "officially switched to supporting Winter's long hair over her short style."

Several posts on the forum lauded aespa's style on this day, with some fans commenting that Winter has especially hit one of her "prettiest" and the most "legendary moments" since debut.

More reactions include:

"She looks like she could be a character from a Harry Potter movie...So mesmerizing"
