Aston Villa's women's team are set to wear the club's sweat-heavy shirts for Sunday's Women's Super League opener against Manchester United.
Villa's male players have criticised the shirts, saying they are uncomfortable because they are retaining too much sweat.
BBC Sport understands Villa had hoped to resolve the issue by this weekend but that has not been possible, and talks with kit manufacturer Castore remain at a delicate stage.
The new claret and blue home shirts are the worst affected, noticeably changing colour in games as they retain moisture and cling tightly to the chest.
The Telegraph reported Villa and Castore are discussing an early termination of their multi-year contract, but potentially only at the end of the season.
