YG has been known to be creative in altering stage clothes, so i dont think this is intentional as YG could easily alter/mix and match the dress. Probably just an overlook by the stylist to use the same cloth without checking who has wore it in prior event
Seems intentional to me, i cant imagine this happened by accident. The exact same outfit with blonde hair, both at Inkigayo during the last day of promotions...Taking almost the same pic next to the same backdrop... The chances of all this happening because of an oversight or communication breakdown instead of a deliberate choice seems awfully low to me lol.
