Save or spend: SaveA suit you wear often has to hold up under frequent cleaning. Because of the fineness of the fabric, high-end suits can't.
So for an everyday suit, choose coarse wool, around Super 100. This lasts longer than a poly blend, since polyester and wool deteriorate at different rates.
With Jos. A. Bank, you'll get 100 percent merino wool, and you can build the suit yourself - from jacket style to fabric.
