This is Kana-chan's oversized t-shirt I bought at the Marui pop-up.
The only sample available was size L, so I bought one size S and one size M.
I'm 153cm tall, and the size S is almost exactly the same size as the one in Kana-chan's illustration! The sleeve length, logo position, etc.
With the size M, the sleeves go all the way down past the elbow!! Also, there's a lot of extra length at the hem. 💦
So I think the size M would be fine for girls over 160cm tall.
