Why everyone wore a pink ribbons...

I can see Cid wore pink ribbon on his arm.

I can see Tifa wore a pink ribbon on her arm...

I can see Yuffie wore a pink ribbon on her four point shuriken weapon

I can see Vincent wore pink ribbon on his arm….

And again I can see Cloud wore pink ribbon on her arm too.

Is that pink ribbons is for Aeris’s death???
