Wearing white to a wedding, a tradition often associated with brides, can be a sartorial misstep, as seen recently with Geri Halliwell's choice of a white dress at her former Spice Girls bandmate Melanie C's wedding. This incident has sparked renewed discussion about wedding guest attire and the unspoken rules of dress code etiquette.

Fashion designer Amanda Wakeley OBE emphasizes that, unless specifically requested by the bride, white should be reserved for the wedding couple. Wakeley explains that the guideline is rooted in consideration and respect, noting that a wedding is an occasion where another person should rightfully be the center of attention. "White naturally draws the eye because we associate it with purity, ceremony and celebration," she stated, adding that wearing it as a guest can unintentionally compete with the bride.

Personal stylist Lisa Talbot echoes this sentiment, suggesting that even if an all-white outfit isn't bridal in style, it can still invite comparisons and appear to be a statement piece, particularly in photographs. Both experts also advise against neon colors such as acid green, fluorescent pink, and highlighter orange, which can be distracting. "Weddings are about celebrating the couple, not making the loudest fashion statement," Wakeley commented.

Red is another color that can be divisive. While not strictly against etiquette, its attention-grabbing nature means it might inadvertently draw focus away from the couple, especially at more formal or traditional weddings. Softer alternatives like berry tones, burgundy, or deep wine shades are suggested for those who wish to wear red.

The context of the wedding—including the venue, dress code, and overall style of the celebration—should inform clothing choices. Wakeley suggests that guests should opt for colors that flatter them and inspire confidence. "The best colours to wear are the ones that you are instinctively drawn to and enjoy wearing and that are flattering to your colouring," she advised. A selfie can help in objectively assessing a color choice.

Talbot recommends soft, romantic shades like pastels, powder blue, sage green, blush pink, or lavender, as well as elegant floral prints. These choices are described as celebratory, photograph well, and allow guests to appear polished without overshadowing the bride. Rich jewel tones, such as emerald, navy, or plum, are also suitable for autumn and winter weddings.

Catherine, the Princess of Wales, is frequently cited as an example of impeccable wedding guest attire. According to Talbot, the Princess consistently chooses elegant silhouettes and refined colors that complement the occasion without competing. Her meticulously tailored ensembles and thoughtful accessorizing strike a balance between sophistication and respect for the event. "She demonstrates that you don't need to wear the boldest colour in the room to make an impact," Talbot noted.

Wakeley agrees, highlighting the Princess of Wales' understanding of dressing for the occasion. "The Princess of Wales understands one of the most important principles of style: dressing for the occasion rather than for herself," Wakeley said. "She always looks polished, but she never overshadows the event or the people at the heart of it."

Ultimately, wedding guest dressing is less about rigid rules and more about understanding the event and honoring the couple. Thoughtfulness in attire, rather than a desire to be the center of attention, leads to more positive impressions. As Wakeley put it, "True elegance is never about competing for the spotlight; it's about understanding exactly when to let someone else shine."
