Not simply sideline activities, Best Rehearsal Outfit once made its mark in previous seasons of the universe "Say Hi", when artists were free to break away from their familiar images, bringing entertainment moments rich in spreading. In the 2025 season, the spirit of "bung xoa" continued to be clearly shown right from the stage run.
Appearing in the general rehearsal, many older brothers surprised with a series of humorous and diverse themes. B Ray's older brother, GILL's older brother and HUSTLANG Robber's older brother all transformed into members of the HKT group, recreating from costumes to typical hairstyles, recalling the familiar image of V-pop. Meanwhile, Otis' older brother chose the image of the character in Avatar with a striking blue outfit, creating visual highlights on stage.
In another approach, buitruonglinh's older brother appeared in a red shirt with floral patterns and "hidden" in the image of the dining table, bringing a feeling of both strangeness and humor. The festival atmosphere was brought by KHOI VU's older brother with the shape of a Christmas tree, while Do Nam Son's older brother made the audience laugh when transforming into a traffic light pole - an image that evokes the saying that once attracted his attention at Live Stage 1.





Besides, the CONGB brother chose the character Sadness in the movie Inside Out, the OgeNus brother appeared with the image of a frog, the Jey B brother brought the winter concept - ice and snow. Dillan Hoang Phan's brother transformed into the character Naruto, while Nham Phuong Nam's brother caused curiosity with a make-up box named "Nam Nen".
Notably, Hai Nam's older brother appeared in the image of the character Ma Muoi, accompanied by a car selling fried fish balls - a familiar image in everyday life but brought to the general rehearsal stage in a surprising way. This series of images was quickly recorded, widely shared on social networks, attracting a large number of views and comments.
Not only revolving around costumes, Best Rehearsal Outfit also reflects the comfort and willingness to experiment of the older brothers before the G-hour. The general rehearsal costumes, although spontaneous, still show investment and become "specialties" behind the scenes that audiences look forward to through each season.
The "Anh Trai Say Hi" 2025 concert will officially take place on the evening of December 27th.
