kenspeckle

"Then there was the kenspeckle figure of The Marquis, as he was known. Dressing normally for odd jobs like droving and fencing, when he attended the sales at Oban he emerged like a butterfly from a chrysalis. Blue Sunday suit, tight brown boots, an oilskin coat hung over his shoulder on a length of stack rope - he even shaved for the occasion."
- 'The Name Game', P.A. MacNab in The Scots Magazine, Dec 2001.

Clearly the coolest synonym for conspicuous around, and generally used in the sense of "Lauren is kenspeckle for her blog, kenspeckle.net," although obviously that's kind of a lie. First used as "kenspeck" in Sir Thomas Cokaine's A short treatise of hunting and as "kenspeckle" in Susanna Centlivre's The Wonder! a Woman keeps a Secret. More here.
