The brown one is definatley late 40s - very early 50s, Juliet style. They look very similar from the late 30s until the mid 50s but the rolled brim and large panache (that is what you call a feather ornament on a hat) are typical of the post war 40s and early 50s.
The blue one is either mid 40s or early 60s but I am leaning towards the mid 40s because of the the rhinestone button trim and that colour. Dark teal just isn't a big colour in the early 60s for hats. If it was navy or turquoise, then I might go that direction. It might also have been worn collapsed, more beret like... hard to be certain without handling it. The label certainly looks too old for the 60s with that tan ground. By the 60s most hat labels are bright white or black and more often than not satin... just not sure.
