Are expensive clothes largely bullshit?
No, I'm not a troll, but I can't help but wonder if clothes are basically like wine -- I can surely tell the difference between cheap and decent, but not between decent and expensive.
I have a pretty high priced wardrobe, mostly because I went crazy on Black Friday 2008 just after the market exploded and retail stores were piling sale on top of sale to dump (my tailor couldn't believe the prices I got on the brands I got...he looked a little depressed). My dress shirts are mostly the popular brands found here, Turnbull & Asser, Hart Schaffner Marx, Burberry, etc. I've had these clothes tailored to my slim build and they look fine.
But the reality is, pretty much any dress shirt looks great to me as long as it is tailored to fit properly. Out of my entire expensive wardrobe, do you know what has consistently gotten the most unsolicited compliments? A deep blue Joseph Abboud slim fit shirt that was $20 at JC Penny and then marked down to $9.99 plus an early bird special sale. I bought it for $7.50 plus tax and never even had it tailored because it was made slim build from the start and hit my shoulders just right.
