A corsage tucked in with the pocket square—maybe more modern than in the lapel?

This is actually a ladies' pearl hat pin piercing the pocket square.
I also love the idea of outerwear with a pocket square, but that is a whole different post.

This gentleman actually did the hand-stitching around the edge of a plain linen pocket square himself. I like it specifically because the stitches are uneven and maintain a very handcrafted look to them.

I'm not suggesting that European men sit around stitching pocket squares while they watch soccer on TV, but soccer is boring, and maybe this activity keeps them from realizing this fact. If I have offended any European men, please send your hate mail to Tyler. (He hates soccer also.)
