I'm now in a point in my career that clothing will be playing more and more of a role. I'm wondering if anyone out there can advise me and or point me to some forums or websites that might educated me on the subject.

I'm wondering what makes a power suit and what price range?

What am I paying for and how can I spot it? I'd like to be able to someday be able to pick apart men's business apparel like I can automobiles ( I've had a head start with automobiles as I took an interest back in 1977). Anyhow, I hear that one area of decernable quality is in the stitching - but what am I looking for in the stitching?

What brands represent a good value?

Should I throw away my $300 Men's Warehouse suits? Or are they acceptable as part of an overall wardrobe?

Shoes - what brands are high quality? How much should I be paying? I've heard that it is worth buying $300+ pairs of shoes as they are reputed to last much longer than lesser shoes. Any thoughts?

Where are the best places to purchase from? (l live in Los Angeles btw)
