Why do people get confused about dress codes?

People often get confused by dress codes for a few key reasons:

1. Terminology – Terms like “formal”, “semi-formal”, “cocktail attire” etc. can mean different things to different people or have nuance that gets lost. Not everyone knows all the terminology around event formality levels.
2. Changing social norms – What was considered “business casual” or “cocktail attire” 20 years ago may be different than today as fashion evolves. Younger generations in particular may default to more relaxed norms.
3. Lack of examples/context – Invites or dress code guidance often just states a phrase like “black tie optional” without visually demonstrating what that means or looks like. People have to interpret based on limited knowledge.
4. Regional/cultural differences – Dress code norms and formality levels can vary greatly depending on country, context and customs. What flies for a wedding in the UK may be different from the US.
5. Personal style/preference – People have different comfort levels adhering strictly to dress codes depending on their personal style, body type or gender expression. There’s room for interpretation.

Dress codes require both specific knowledge of fashion terms and norms as well as nuanced cultural understanding. For people lacking experience or examples to refer to, it can come across as rigid and confusing rather than guiding. Providing visual references helps alleviate confusion vastly.

Should couples wear complementary colours?

Here are some tips on whether couples should wear complementary colours:

• Matching or complementing colours can look very coordinated and elegant when done tastefully. It makes a couple look cohesive.
• However, it’s not strictly necessary. Wearing contrasting colours or completely different palettes is fine too. The most important thing is that both outfits follow the dress code.
• Subtle colour coordination works better than exaggeratedly matched shades, which can look over the top. For example, if the woman wears a navy dress, the man can wear a navy tie to complement.
• Black tie events offer easy coordination since the traditional tuxedo/gown palette already matches. Accents like cummerbunds, pocket squares etc. can coordinate.
• The level of coordination also depends on the formality of the occasion. A black-tie gala calls for seamless formal harmony between a couple’s outfits. Meanwhile, relaxed events allow more creative freedom.

Colour coordinating is optional, but can add a special touch when done strategically. As long as outfits suit the dress code, it comes down to personal preference on complementing couples’ colours or not. Subtlety is key.
