This year has seen BTS top charts, break records, and now they’re designers, thanks to a recently-launched collaboration with Line Friends.

BTS and the character brand, which is a subsidiary to the Korean messaging app Line, launched their BT21 collection last Saturday (Dec. 16) in New York City and Seoul. Fans came out in droves to the stateside location in Times Square, with Line Friends reporting an estimated 35,000 customers visiting its flagship location on launch day.

Throngs of fans crowded the New York store early in the morning with 2,000 lining up prior to opening, and the store stayed open late for those who were unable to make their purchases prior to the usual closing time of 1 a.m. Despite snow flurries in the area the day before, fans said that they began lining up at 4 a.m. for the 9 a.m. launch where the first customers were greeted by cheering store employees. The slow-moving-but-organized line almost wrapped around the entire Times Square block.
