Unless you are going to the Royal Wedding, a hat like these will definitely steal the show
When you get invited to a wedding, you want to be a kind and courteous guest, grateful for the invitation and happy to be among friends and loved ones to share the couple’s special day. The one thing you don't want to do is be the one that everyone remembers for causing problems on someone else's big day.
An age-old concern when it comes to getting ready to be a guest at a wedding is always "what do I wear?" If you're lucky enough to be in the wedding party, then obviously the decision is made for you since the bride and groom will choose the attire for you based on how formal the event is. But if you're not in the party, what's right to wear as a guest?
One thing no bride wants to see is another woman wearing a white dress. While no other guest will confuse the bride in her gown with a guest in a white dress, avoid the potential whispers and glares. You don't want to be known as "that woman" who shows up the bride. If possible, try to find out the color or style of bridesmaid dress, and stay away from it. You don't want to come off as jealous to not be in the party.
Men can almost never go wrong in a suit, unless the invitation specifically says the event is black tie. If it is, get ready to rent a tux. If the event is white tie, considered the most formal kind of event, don't show up any other way.
If you're in the wedding party, a quick drink to relax the groom isn't out of the ordinary these days, but don't overdo it. You don't want to be the person to stumble down the aisle.
At countless weddings, there is one guest or group of guests that have too much fun and take too many trips to the bar. You don't want to be that person, either. Not to sound too cliche, but be responsible when it comes to being a wedding a guest, and no one will regret having invited you in the first place.
