We all know that TWICE might be not MLB model anymore. After the announced of EXO is the new model of MLB, one by one of Twice members, they stop using the brand. If they still the model, they might use it regularly on their vlive/on the airport like they usually did last year. So there's possibility, they not the model anymore.
But some of the member still use it. On Twice 1000th day vlive, during the entire vlive, you can see Dahyun cover the shirt but she use it openly after they finished recording on Inkigayo. If they still the model, why would she cover it? So it is true Twice x MLB is over. Also she was seen using MLB cap when theh met Wheesung on recording studio. As well, Nayeon was seen use the brand when she went "date" with Jeongyeon. And she use MLB cap and sweatshirt when they promote WIL on radio.
I think some of the members still use the brand despite them the "ex" model of MLB. I think they might find the MLB items comfortable to use. No TWICEXO collabration then TT
