Next Saturday's game at home to Bristol City will be 'True Blue Day', with Spireites fans urged to wear blue to show their support for the club.Spireites chiefs want to see as many fans as possible wearing blue at the Proact Stadium, whether it be a replica home shirt, t-shirt or scarf.
The dress code in the corporate areas of the stadium will also be relaxed on the day, allowing those in the lounges to wear replica shirts.
Spireites chief executive Chris Turner said: "We want to generate a party atmosphere to celebrate what has been a fantastic season and it would be fantastic to witness a sea of blue in the stands when the teams run out.
"There is a limited stock of home replica shirts on sale in the Club Superstore and we also have some blue t-shirts and scarves available. The players and management have done superbly well to put us within touching distance of the play-offs so let's make True Blue Day an unforgettable occasion."
