Such requests will be made clear on the wedding invitation and the couple's wedding website.
Unless all-white outfits are explicitly required for the wedding day, wearing a white outfit or one that even features a white pattern is a bad idea, as doing so can appear rude or disrespectful to the couple.
Wedding Guest Outfit Etiquette
If you're struggling to decided on a dress to see you through wedding season, here's a few rules on what not to wear so you don't get in trouble.
Folklore says that wearing red at a wedding means you slept with the groom.
Casual attire like jeans and flip flops should always be avoided.
Any colour that could be picked up as white or cream - even if it's not.
Most would agree that your cleavage needs to be covered.
Wearing white is a massive no-no if you're not the bride.
