I don’t wear women’s slacks at all and really never have. I wear men’s jeans and/or khakis. Even back in the late 70s when I was in HS and our uniform was changed to allow us to wear slacks I had a tough time finding ladies/women’s slacks to fit properly.
The last time I could get my hips into men’s pants was 1980 ;-).
I too have been wearing men's jeans since my early twenties. I am wearing now, as I type.
Dress slacks are a different matter. There was a brand ( Karen Scott) that had well fitting lined pants that were perfect for the office. They were completely machine washable in hot water and were as durable as a knight's chain mail. I didn't even need to try them on. I bought them right off the rack...but...Macys doesn't carry them any more. ( sniff)
I am retired now so I only need one or two pair. I now sew my own. I have the time and I don't mind.
By the way, I have missed you, Amelia, and SoftballmominVA over on the education threads. You guys kept things interesting.
