I feel that Romi is overacting since she could use the new uniform as a spare or, use 3 days the new uniform and use 2 days the old uniform and vice versa, or I don't know, i don't even know what the issue of the number of uniforms per student in Japan is like.
The next day...
Uh-huh!
Hmm. And we don't have any smaller sizes.
I wanna try it on!
Swff...
So it's all right to throw away your old one.
Baggy
Loose
You probably didn't like it because Mommy's so bad at sewing...I'm sorry.
Mister Principal, it's too big...
I like my old outfit.
Your uniform's finally arrived, Arisu-chan.
Oh? Then what will we do with this uniform?
Good for you for getting a new uniform, Chiyomi!
Huh? Where's your new uniform, Chiyomi-chan?
Chiyomi likes this one better after all! Mommy sewed for me!
