Here is one of my treasured pieces I never got around to wearing. It's a double breasted black pinstripe suit from RL Black Label.
Made in Italy by Raffaele Caruso, fully canvassed construction, 100% wool, double vented, flat front trousers w/ side tabs, and the wonderful slim Black Label fit.
This is one of the few double breasted suits that will fit slim!
The suit is tagged 42L, but fits more like a 42R.
