I shop about one every other month for work clothes. I have always liked Brooks Brothers for work clothes. You really can't go wrong and get something that would be inappropriate, at least in my office.
I obtained a Brooks Brothers charge card about a year ago to take advantage of a 25% off offer when I was in Chicago last year and forgot some essentials for a dinner. Since then, I rarely use the card, but I keep it for one reason. About 6 times a year they send me emails with discounts that only apply when I use the charge card. They also send me a $20 gift card in the month of my birthday. No restrictions and no purchase minimums, just $20 to spend. So I went to the store in Park Meadows on Sunday and got a great belt for $58 - 40 in discounts = $18. I was a happy shopper.
The folks at this particular store have always been helpful and friendly.
