Oh, the specter of good taste threatens to raise its hoary head yet again!
Without laying down the dogma, I must say that to consider these ties as loud or offensive pretty much misses the point--and it's an exercise that, frankly, hadn't really occurred to me. I'm afraid the truly sublime nature of the silks and printing may not come across here (they seem kind of flat in the picture, much more vibrant in real life). They are, as objects, alluring and attractive in the most elemental way. Whenever I wear one of the Hermes ties people are drawn to them. And they don't say, Wow! Kind of a bright tie today, huh? Rather, they admire them and want to touch them and just look at them. One of the basic things that sets the scarf print apart from other ties is the lack of a repeat motif. It's an unusual feature in menswear. Almost everything we wear is built on the foundations of symmetry and repeating patterns. Despos touches on this with his tale of the vest. As he suggests, what made the vest successful was the unexpected way the figures came together. And I think FNB is right to invoke the term classic. These ties have been worn for years and are, simply put, part of the repertoire we have at our disposal when we get dressed. Just like dots, the rep tie, or small woven patterns. Of course they have rather more difficult associations and meanings than any of those, but they remain part of the canon. Wearing the scarf print is not a simple thing. But like an especially complicated maneuver in diving or gymnastics, it presents a degree of difficulty that really pays off when executed properly. So, please, let your freak flag fly!
I think the last time I wore any of these it was the Hermes Kachina print on the white background. I can't remember exactly what the pairings were, but I think it was a fairly quiet look in keeping with the subdued colors you see there. I think Newton is right to recognize the importance of combining these ties with other patterned pieces. About the snottiest look I could imagine would be the haughty French banker look of charcoal suit, white shirt, and a black scarf print with the rococo gold and red flourishes (but, again, that's an image you might want to play off of--as the Versace tie with the insane marine motif does).
My two cents.
