The official website explains the beret situation.

It was announced that the members-only event of MCZ's fan club "ANGEL EYES" will be held from 11/2 to 11/3 for 3 shows.

A video of the members making this announcement is posted on X.

Mononofus who saw the video voiced their opinion that the berets (white berets) worn by the members were custom-made.

This "white beret" was sent to members when they joined the "ANGEL EYES" fan club.

However, the size of the beret is not adjustable, and it is originally designed to be small, so many mononofus cannot wear it on their heads. (It doesn't fit on my head either.)

This time, in this video, the members were wearing the "White Beret" so cutely (and in the perfect size) that some mononofus suspected that it might be a different design from their own.

The official fan club website, seeing the comments, added the following post yesterday.

The white berets worn by our members are exactly the same as your white berets.
