It's a common tradition to keep the wedding dress a secret from the groom before the big day, but one woman says one of her friends ruined the big reveal.

In a post that's going viral on the parenting forum Mumsnet, a bride-to-be explains how a wedding-dress fitting led to an unwanted Facebook post from one of her bridesmaids.

"After finishing the appointment and getting home I saw that she had posted a photo of me in the dress on Facebook (during the appointment so it had already been on an hour or two when I saw it) and tagged my partner in it saying she bets he couldn't wait to marry me and how lovely my dress is," a user by the name of Titsntats wrote in the post.

When the bride-to-be asked her friend to remove the photo, she says the bridesmaid wasn't very accommodating. She wrote that it was especially upsetting since it was also supposed to be a surprise for her father, and that she had been "very body conscious" and "anxious" throughout her search for the perfect dress.

"When I asked her to remove it her response was 'it doesn't matter if he's seen it he's a man so he will have forgotten what it looks like in 5 minutes time,'" she wrote. "My dad had also seen it as well and it was going to be a surprise for him on the day too."

She says that she has conflicted feelings about the situation, and asked the forum members to share their thoughts.

"I just don't know what to do or how to feel! I am so gutted that it now won't be a surprise to my partner or my dad," she wrote. "She knew how much that meant to me and the only thing I had asked for was that details of how I will look on the day were kept a surprise from my dad and partner."

Most commenters were on the bride's side, saying that they would be "furious" and "angry," and some even suggested that she should "sack the bridesmaid."

"She definitely wouldn't be my bridesmaid anymore," one person wrote while another added, "To break her promise and your trust like that is horrible and not what a friend should even think of doing."

Etiquette expert Diane Gottsman told Brides that you should always ask permission first before uploading photos of the couple. She also says that it's always up to the couple to post the first photos, unless stated otherwise.
