Bride forces friend to change hair colour for wedding.

Bridesmaids: Matching dresses, matching makeup, matching hair styles… matching hair?

A bridesmaid has been told she needs to dye her hair if she wants to be in her friend’s bridal party.

The 22-year-old shared the request on Reddit to ask users whether they thought the bride was being reasonable.

“Am I being reasonable here? I’ve never been involved in a wedding before so I’m not quite sure what’s expected of me,” she said.

The bridesmaid shared how the request came via a group email where the bride discussed the “look” she wanted.

“Bridehairthrowaway, you’ll need to dye your hair for the day, I’ll take you to my hairdresser and cover the cost :),” the email read.

The bridesmaid shared how, as a natural ginger, dying her hair may be more difficult for her than the other girls.

“I’m a natural ginger, so it’s not like I have an outrageous hair colour, although Ella (the bride) and her other bridesmaids are all brunettes,” she said.

When she approached the bride with her concerns, the bride said her hair would “clash” with the wedding colours and that having a ginger in her wedding party would “take away from the cohesiveness of the group”.

She then said that brides “get a veto over pretty much every aspect of her bridesmaids’ appearances”.

The bewildered bridesmaid told the bride she wasn’t “comfortable” dying her hair and the response was that she hoped the bridesmaid would “reconsider”.

The post has received over 800 comments in less than a week.

Top commenters have pointed out that a drastic change in the bridesmaid's hair colour would probably draw more attention to her than if she had left it.

"Dying her hair will actually make the bridesmaid stand out MORE. Everybody that knows bridesmaid will be more drawn to the change, it will actually detract from the bride to have such a big appearance change like that on display," one user said.

Another user said that although brides had sway over what their bridal party wore, making further demands bordered bridezilla territory.

"Maybe what you're wearing but not your actual appearance. This is some serious bridezilla nonsense. Tell her that you'd have to live with this change for long after her wedding day is over and you are not willing to do it," the user said.

"She'll stand out anyway. She'll be wearing a wedding dress."

A third user was simply outraged at the audacity of the bride.

"Who asks this? I think other than asking if she would change her skin color, this is up there with the most WTF request I've heard for a bridesmaid."

Even an upcoming bride took to the site to explain how she'd never expect that of her wedding party.

"You are not being unreasonable at all! I'm planning my wedding now, and I'd NEVER ask bridesmaids to dye their hair! This is bridezilla-level shit, like she's scared of being upstaged by her 'maids, so she's making crazy demands," the upcoming bride wrote.

"She's being ridiculous. Tell her you'd love to be a bridesmaid, but you won't dye your hair. And if she insists on the hair, you should decline to be a bridesmaid."

The original poster replied to this user to say she was considering wearing a wig but felt even that was going too far.

"Thank you for confirming I'm not crazy. I was considering offering to wear a wig, but I even think that's kind of weird. She was just so casual about it she made it seem like a normal occurrence."

The issue is yet to be resolved as the original poster continues to reply to comments.
