Finally, when it comes to attire, a good rule of thumb for visitors is to keep things cheerful and colorful; don't wear gloomy colors-a it's noon event, after all, and you're celebrating! And if you're not the bride, avoid wearing white; it's designated for the stunning bride-to-be. However, while it's nice to be inclusive, there are some types of events where wearing white would be appropriate. For example, if you were attending a wedding ceremony on a cold winter's day and the only other guests attending were going to be seated according to age, then wearing white would be appropriate. On the other hand, if most of the attendees at your lunch were in business attire and you showed up in jeans, a t-shirt and sneakers, they might think that you were there to give a speech rather than eat, so stick with comfortable but still dressy clothes. In conclusion, yes, you can wear white to a bridal luncheon. But like any other social occasion, you should consider the people involved before deciding what to wear.
