Town are set to wear a black and grey third kit at Wigan Athletic on Saturday, a strip which will not be made available for fans to purchase.
The home side’s blue and white striped home kit clashes with both Town’s first and second strips, hence the move to a black and grey striped shirt, black shorts and black socks.
The kit won’t be made available for fans with only a small number having been ordered from adidas for the first team.
Club head of retail Paul Macro told the club site: "Unfortunately, we have not been able to retail the third kit and make it available to purchase for supporters.
"Our third kit is first-team issue only, so unfortunately it is not feasible for us to retail it within the current terms of the club’s contract with adidas.”
The Blues have previously worn black third kits in the past, including in 2006/07.
