Been rocking a silk knit tie lately? You might have noticed that it's pretty tough to find a matching pocket square — that's because they're not all that easy to make. Which makes these MS & Co. Silk Knit Pocket Squares ($35) all the more special. The result of dozens of tests, they measure 6.5-inches square, are made from 100% silk, and come in navy, white, and pink. You can thank us later.
