衣装チェンジじゃなく、わざわざ同じ服と帽子を買ったメリー
ただしサイズは微妙に違う。　胸のところとか。

ちなみに友人まるはち氏（"user/5153759":[/artists/91906]）の誕生日絵でもあります。　もう過ぎましたけど

It's not a costume change, it's just that Merry purposefully went out and bought the same clothes. But the size isn't quite right. like around the bust and stuff

By the way, this is also a birthday picture for my friend Maruhachi. It's late, though.
