Wow, sharp suit.  Nice short jacket which accentuates the longer, slim legs.  Of course one must have the proportions of the model to pull off this look - definitely not for a more portly gentleman.

I like my suits to fit in this manner.

I have to agree with D.
VERY Modernist.
Clothes-wise, I used to have a theory that the English 60's reprised the '20s which in turn reprised an aspect of Edwardian dress.
Frankly it's a theory with so many holes in it that I keep quiet about it these days.
MY Modernism is a vague global thing with it's roots at the turn of the 20th Century (although, when in the mood, I'm happy to bullshit my ideas back to the 1860s..). It has its roots in the painting & architecture which came into bloom pre- WWI and promptly got stalled - Then it regrouped in the '20s & '30s, but got badly hit by WWII. Finally in the period maybe starting 1949 it all began again, resulting in everything I love happening in the early-ish  50's through to (when?) 1962 tops.
Just a POV from me and one which is only based on gossip from London & what little I have been able to pick up about bits of the rest of Europe at this time.
Enough!

nice ad.  That suit looks very much like my Thom Browne one.  Pics like that completely redefine "sack suit" in the way the term is bandied around nowadays.  Mos definitely mod as f@ck

I dont prescribe to any set aesthetic that has a definable term.  But I definitely draw from elements that fit with my tastes.  So, no, not a "trad" but have an appreciation and incorporation of original ivy trad. 

and we both know what a great song *that* is
