I saw a shaggy waistcoast (or faux fur vest) in the early 2000s in a Bay Area boutique. It was from Italy. I wanted it then. I had the money, but not the courage to buy it. I regret that. I finally took the plunge and bought one in Nov., but it is not as fab as the one I saw a decade ago.
One time I did impulse purchase an item that has stood me very well. I was in London on a business trip and bought this furry coat (again from Italy). It was a splurge even then (365 pounds).
I got the coat in 1996 and have worn it every year since then, and it's held up! So now it's become my cheapest coat ever, given the usage, even cheaper per year than something from H&M.
I share my story to illustrate Angie's point -- jump in early if you love it.
