During the 1970's I worked at several men's clothing outlets in retail sales, both department stores and specialty shops. I started in the men's clothing department at Sears, worked the same job at Rose's department store, and worked at Men's Warehouse (You may have seen their commercials on t.v.), a national chain of men's clothing stores that deals exclusively with "business attire" featuring upper scale garments at reduced prices. Naturally, this also includes accessories like shirts, belts, shoes and the like.
From experience, I can tell from a glance by looking at a man's suit and dress, whether he's wearing a low end "off the rack" suit, or whether he's wearing a more expensive one that has been properly fitted and tailored. It's like being able to spot the difference between a guy who is works as a public defender and can only afford a suit at Walmart or Sears, and someone working in the DA's office, as well as a bank manager or stock broker type who can generally afford much more expensive clothes.
As for tele-evangalists like Irvin Baxter, I can assure you that he doesn't buy his suits "off the rack" at Sears. I have seen him up close in person at a church where he "performed" in Humble, Texas. He arrived in a Lincoln Town car with a security entourage, and I estimate the cost of his tailored suit at around $800 dollars. His shirt and tie were silk, and you can kick out another $200 dollars for his silk pocket handkerchief, socks and expensive leather shoes. At over one thousand dollars, definitely bank manager attire.
Just thought I'd point out the difference between "regular" business attire, and someone who dresses in a particularly "luxurious" style of attire that says, "I am successful, and I am affluent, and I spend lots of money to look that way". Irvin Baxter definitely spends lots of money to look the way he does.
You guys decide for yourself, whether or not it's appropriate for a "man of the cloth" to dress in that lavish a manner. I'm just pointing out the obvious.
