Adach Yumi was an elementary school student and didn't wear a sailor suit in 家なき子. She was a junior high school student and wore a sailor suit in 家なき子２, but there are two white lines on the collar of her school uniform, and her scarf was blue, not red.
@Muz1234, should you ever wonder how to thank those members who keep helping you so courteously, I suggest you reply to your threads with a short expression of gratitude or at least click some of the reactions ("Like" or "Thank You").
