The Voice of the Philippines answers the issue on judges not changing their clothes.
Although it's too obvious that the audition for The Voice PH was done on the same day, in my my opinion, I just find it unlikely to see its judges wearing same clothes over and over again. The Voice PH's blind audition was first aired or premiered June 15 until July 20, again they were wearing same clothes.
As compare to other reality talent search by ABSCBN like PGT and X Factor, outfit of The Voice judges caught the viewers attention and sometimes make fun of them.
With that issue, ABSCBN's gag show Banana Split made a parody of Sarah G., one of The Voice judges to prove that they indeed change their clothes as will be explain from the video below.
