England Women have asked Nike to change their all-white kit, as the shorts are "not practical" due to periods.
The Lionesses have worn their own strips over the past three years, having previously turned out in the same kit as the men's team.
But England players have now raised an issue with their white shorts.
Sarina Wiegman's side turned out in their home colours in their Women's Euro 2022 opener against Austria, a 1-0 win at Old Trafford on Wednesday.
But winger Beth Mead, who scored the only goal, revealed the team were concerned by the possibility of red spotting showing on their shorts during their periods.
"It's something we've fed back to Nike," she told The Telegraph. "Hopefully they're going to change that.
"It's very nice to have an all-white kit, but sometimes it's not practical when it's the time of the month.
"We deal with it as best we can. We've discussed it as a team, and we've fed that back to Nike."
Mead said she was "pretty laid back" about which alternative colour Nike might opt for, while Georgia Stanway added the concerns were forgotten as soon as the players took to the pitch.
"It's difficult, because we associate England with white," Stanway said.
"The home kit is unbelievable, it looks really nice. I think that's something that we can speak about as a full squad, as a group of girls.
"I think next year there is potentially a colour change going in. I think it's hard, because once you're on the grass, nothing else matters.
"I think we have a good doctor who likes to look after us. As soon as the adrenaline comes in, you could be naked and nobody cares. That's what happens when you're on the pitch, you forget about everything."
