THE QUICK ANSWER
- Find the code: check the invitation and the couple's wedding website.
- Avoid white and ivory unless the couple asks for it.
- Match the time: lighter and brighter by day; darker and more polished in the evening.
- When in doubt, dress up a little and choose shoes for the ground.

Guest rules for every wedding
- White, ivory and cream belong to the couple. Avoid outfits that could look bridal in photos.
- Check the website. Couples often explain the dress code, venue and terrain there.
- Dress for the ground. The Knot advises block heels, loafers or sturdy sandals on grass or uneven ground, and warns that stilettos are a poor choice outdoors.
- Respect cultural and religious traditions. If the ceremony follows a tradition you don't know, research it or ask. Some ask for covered shoulders or heads; some have colours guests should avoid.
- Bring a layer. Churches, marquees and evening receptions can be cold.
By season
- Spring and summer: lighter colours, florals and breathable fabrics such as linen, cotton or chiffon.
- Autumn and winter: jewel tones and deep neutrals, velvet, a tailored coat, and tights or thermal layers.
- Hot climates: loose shapes, natural fabrics and a hand fan. Our temperature guide covers in-between weather.
Wearing an outfit again
A good wedding outfit can be worn again. Choose a dress or suit you'd wear to two or three different dress codes, then change the shoes, jewellery or tie to match each one. A navy suit or a dark midi dress covers semi-formal, cocktail and, with the right accessories, black tie optional.
Quick questions
Can I wear black to a wedding? Usually yes, especially in the evening. Add colour or texture so it feels celebratory, and check cultural norms.
Can I wear the same outfit to two weddings? Of course. Change the accessories if the guests overlap.
No dress code on the invitation? Look at the venue and time. An evening venue in a city points to cocktail; a daytime garden points to semi-formal or dressy casual.
Is a jumpsuit OK? Yes, from casual up to formal, in a fabric that suits the code.
