J.C. Penney used to be an excellent place for business clothes. In the Stafford/Stafford Executive lineup they had fully lined suits, nice oxford shirts in true 1/2" increments, husky, tall, fitted sizing, and their shoes were OEM Johnson and Murphy which at $130 in the 80-90's was still pricey; much less than the Johnson and Murphy branded ones...they were identical otherwise.
I had started buying their suits when I was 15 back in 1986 and up until I left banking in 2000 every year. Since then their suits have become unlined (you could still special order lined suits at the time), their shoes not much better than average and their pants especially thin and cheap.
My last 'hurrah' was getting the Stafford Sharkskin trousers at $15-20 a pop (normally $65 on clearance). Since then there is nothing there I'd consider anything but something a High School kid would were on an interview.
Now their Levi's section is awesome and they have some really cool graphic T-shirts with all the old brands and signs...the material they are made out of is also good and usually Hanes Beefy-T quality or better.
The stores around here are in the same footprint but internally downsized. They had an article on this somewhere online and how bad that is for a store and gaining customers. You see lights out at times and other crap that should be maintained.
I don't see them surviving.
