Not a thrift store bragging story, but I picked up a $1400 John Varvatos mainline blazer for $255 at the warehouse sale in New York yesterday. Gray wool herringbone in size 38R. Made in Italy. Fits me perfectly. Lush material, double-vented, fully-lined, half-canvassed, etc. I think it even has horn buttons. Remember the tweed blazer from Uniqlo that was featured in GQ a couple months ago? It's NOTHING compared to this thing.
It was about the only nice thing they had at the sale in my size. Shirts sucked (odd fit, and see-through material), and so did the suits (mostly black pinstriped).
