If stuff like that matters to you...a good suit will cost a bit/lot more, but they do last....buy three cheap suits, or one quality suit. Unless you con't take care of them. Or get fat. There is a difference in material and cut, too. Sit on the back row in church...you can easily pick out the (few) people that have quality suits.
My suits aren't that expensive, around $900, by the time I buy some ties, shirts, etc to go with it, usually drop $1600 or so...but, practically everytime I wear one, to church, wedding, whatever, people will say something about it...folks notice. (And one is just a plain charcoal goes-anywhere suit).
I get my stuff at Ashworths in Fuquay...nice folks and worth the trip. They know their stuff...it's a real, locally owned mens shop, not a chain.
