Wedding Etiquettes and Wedding Guests
For guests: Avoid wearing anything white. This is because the bride is going to wear white and we would want her to stand out. if a number of wedding guests are wearing white, this will draw the attention away from the bride as she wears her wedding dress and bridal jewelry and she may even just look ordinary, which we would want to avoid.
For brides: Keep in mind that you cannot insist your guests to wear a specific type of dress or suit. Always keep everything practical when it comes to their clothes and do not allow them to wear anything, which is too expensive for them to buy. This is necessary since if you demand too much, they may consider not joining your function.
