What the Groom Should Wear: Colour, Cut, Fitting

August 21, 2026 · 8 min read

The groom’s outfit is decided in three steps, and the order never changes: colour, cut, fitting. Colour is set by the venue and the hour, cut is set by movement rather than by body type, and the fitting has to be done with the actual shirt and the actual shoes. And unlike the dress, the real risk here is not looking bad — it is disappearing in the photographs: in a dimly lit room a black suit merges with the background into a single dark shape. Which is why this decision gets made alongside the colour of the dress, with the venue’s light in mind.

When to start

The suit does not need the calendar a dress needs, but it is not a last-week job either: alterations take time, and so does breaking in shoes.

How these steps sit inside the rest of the plan is in our 12-month wedding planning checklist.

Colour: the venue and the hour decide

Colour is a question of light before it is a question of taste. The same suit reads as two different outfits in a garden at four in the afternoon and in a ballroom at midnight.

One rule: the suit’s colour does not compete with the white of the dress, it competes with the wall behind you. Account for the dress’s shade too — a pure white shirt next to an ivory dress photographs as two different whites. The decision order on the dress side is in how to choose a wedding dress.

Cut: movement, not body type

The cut discussion usually starts with "slim or classic" and starts in the wrong place. The right question is this: you are going to sit, hug, dance and probably pick up a child in this suit for eight hours.

Fabric and season

Fabric is the most regretted decision in a groom’s outfit, because the consequence does not show in the photos — it shows on the arm: sweat.

Rent, buy, or have it made?

All three are normal, and the decision comes from three questions rather than sentiment: will you wear this suit again, how closely does your body match standard patterns, and how many outfits do you need?

A second outfit for a rehearsal dinner or a separate ceremony day is its own budget line, not a variant of the first. You can test how the lines add up in our wedding budget calculator.

Details: the only part that shows up close

The suit itself is a silhouette in a photograph; the character comes from five small pieces, and every one of them appears in close-ups.

What does the suit do in photographs?

The groom’s photographic report card comes out differently from the bride’s: a dress reflects light, a suit absorbs it. That has three concrete consequences.

Your photographer shoots the groom from chosen angles and mostly beside the bride; the phones at the tables shoot him all night on his own, mid-conversation and mid-laugh. Those frames stay in people's galleries because nobody thinks to send them — a QR code on the tables is the simplest way to collect the groom's real photographs into one album.

What guests wear is a separate question and it sets the dress code you print on the invitation; we covered it in what to wear to a wedding. The two or three habits that make guests' phone frames usable are in wedding photos with your phone.

Conclusion

The groom’s outfit is decided in three steps: colour, cut, fitting. Choose the colour for the venue’s light and the hour — navy beats black in a dark room; test the cut by movement, because if the shoulder is wrong the suit is wrong; and take the shirt and the shoes to the fitting. Decide between renting, buying and making by whether you will wear the suit again. And remember this: the most natural photographs of the groom that evening will not be the poses the photographer sets up, but the frames shot from the tables.
