Hi to all attending the Classic this year, here is so info about the dress code from the organisers.
Le Mans Classic celebrates "the" Automobile and it is an interactive play…
On the occasion of Le Mans Classic, the 24-Hour-circuit produces a set paying tribute to fifty years of its history celebrated by Le Mans Classic. Modern cars are prohibited inside the circuit to preserve this unique past times atmosphere. All the actors, drivers wherever they are –on the track or inside the paddocks-; club members; partners and their guests endeavour to perform on the stage.
The public (over 70,000 people in 2006), is encouraged to do likewise. Thus, we kindly ask the spectators to visit Le Mans Classic correctly dressed up. The actors of this temporary show, who come often from abroad, will for sure appreciate to receive in return their visitors' tribute.
To visit the paddocks if no proper dress code is enforced, 'jacket and tie' is preferred. On the other hand, tracksuits, shorts and bare-chested are strictly prohibited.
