Just don't buy a black suit. A nice dark charcoal gray or dark navy blue is good for your first suit.
yeah everything I have read also says no black. Most say charcoal as a first suit. I'm wondering how much to spend.
I wouldn't go out and buy a suit just to say I had one. Not sure what they cost in the States, but here, a reasonable suit would be about 300€.
That's more money than I'd spend just to say I owned one.
If I was someone with an unhealthy diet, presumably overweight, and I didn't need to buy a suit at the moment, I would wait. You don't want to lose a bunch of weight and have a suit that doesn't fit.
I would say the list price for a basic decent suit is generally about $400-500. You could get a cheaper one at Filene's or Nordstram Rack or something like that. In general, I think buying a cheap suit is a bad idea unless you know for sure that it's a bargain.
