Help Dating some hats

[Ella Sparkles]

Hi everyone I am hoping that someone can help with the dating of these hats I just bought. I just starting collecting them, they have a Hatters Union label on 2 of them. I don't really know the "types of hats" I just thought they were fun. Any information you care to share would really be useful to this novice.

These look late 50s and early 60s to me.

I agree, late 1950s to early 1960s.
