Such idea was suggested by the expert of etiquette, representative of the association of Romanov's family members Ivan Arzishevsky.
According to him, dwellers of St. Petersburg must be responsible for the correspondence of their outfit and and the "place status". This measure concerns tourtists as well. "We won't put on bikini if we go to Mariinsky Theatre only because it is more comfortable. And Petersburg not only has theatres, but also Hermitage, Russian Museum, Nevsky Prospekt",- explained Arzishevsky.
The expert also pointed that citizens should understand what clothes are more suitable for cafe, theatre, cinema, museum or party. He suggested to institute the system of "neat" restrictions for the citizens and punish the troublemakers.
But Arzishevsky can't say anything about the exact rules of outfit choice. At present time, the authorities of St., Petersburg don't participate in dress-code discussions, therefore the issue of its legalization remains open.
