We popped over to Belgium to check out classical music's newest concert hall.
This season's fashion trend is the humble polo neck jumper. But who do we have to thank? We salute the conductors who have been holding firm with these ultimate items of smart-casual dress.
David Zinman, going polo
Proving that a jumper that gently strangles its wearer is the match for any set of white tie and tails.
The very dapper Vladimir Ashkenazy
A tireless advocate of the turtle. This one's as elegant as his Chopin.
A wind-swept Andre Previn
What could possibly balance those spectacular flowing locks? It has to be a faintly checked turtle neck.
The impeccable Michael Tilson-Thomas
Very GQ, MTT.
The living-legend that is Neville Marriner
And a white polo neck remains this nonagenarian's staple.
The open-collar-eschewing Helmut Rilling
For this legendary German conductor, polo neck and French cuffs go together like Bach and vibrato (in his opinion).
The master of the roll-neck sweater, Leonard Bernstein
Burgundy turtle and harpsichord. A classic combo.
Leonard Bernstein (again)
Yep, Leonard Bernstein really liked a polo neck.
Boom, Bernstein hat-trick!
Might he be singing a power ballad?
This is getting out of hand
That belt. STOP IT, Lenny.
OK then, one more
Leonard wins. Time to go home, all.
With looks like these, no wonder the turtle neck is leading the fashion world this season
And we now know who to thank.
