+1 - but then again, it was always going to be a difficult topic.
There's a lot more "peacocking" going on in menswear nowadays, quite a lot of it inspired by #menswear on Tumblr and so on.
I think that the trick of "no effs given" is essentially sprezzatura, as used in dressing and appearance.
However, the problem is that there's an awful lot of "false sprezzatura" out there - where people try to look nonchalant and effortless but where they have, in fact, put a great deal of thought and effort into their clothing, and an awful lot of "faux sprezz" photos pop up in the #menswear feed on Tumblr, such as people wearing ties where the back blade is much longer than the front blade, or where the back blade is tied alongside, instead of behind, the front blade of the tie, or where buttondown collars are deliberately left unbuttoned (as a few, small examples).
In terms of appearance, it can be a very fine line between real sprezz and false sprezz, so it can be difficult to tell whether one is "no effs given correctly" and the other is not!
Really, people are purposely tying their ties incorrectly? I just thought they weren't good at it.
