I hear you, but the way I see it in my mind is when I say "hey, got like 3 friends coming over today", and she immediately goes to change into that instead of the original pajamas and sweater she was wearing, I see it as her wanting to flaunt herself to them
My wife is older but she has done same thing forever, I enjoy it very much now.my lady wears a lot of mini skirts with no panties, never anything underneath.
