The 2025/2026 Wedding Guest Style Guide: What to Wear to an Irish Wedding

You just received a stunning invitation to an Irish wedding. The anticipation is instant, but it's usually accompanied by a familiar question: "What am I going to wear?"

Changing the world of wedding guest fashion is complicated, at the very least, with the distinctive Irish charm and the unpredictability of the Irish weather. Whether it's a smart city hotel, a stately country mansion, or a rural barn, you wish to be dressed stylishly, feel at ease, and above all, be suitably attired for the event.

This article will take you through all you need to know to be the best-dressed wedding guest in 2025 and 2026.

Decoding the Dress Code

Your invitation is the first indication. Irish weddings usually include a dress code, but what does it mean?

Black-Tie

This is the most formal dress code. Red carpet glamour is what you're aiming for!

For Women: A floor-length evening dress is traditional. Alternatively, wear an extremely formal and elegant midi or cocktail dress made from a luxury material.

For Men: A classic tux is a must. This entails a black or midnight blue tuxedo, a white dress shirt, a bow tie, and smart patent leather shoes.

Formal / Black-Tie Optional

This is slightly less formal than Black-Tie but still requires a polished and elegant appearance.

For Women: A cocktail dress, a midi or formal dress, or a stylish, dressy jumpsuit or suit are all great options.

For Men: A tuxedo is not required, but a dark, properly tailored suit with a tie is a must.

Cocktail Attire

This is one of the most popular options for Irish weddings. It is the perfect combination of formal and celebratory.

For Women: A knee-length or midi dress is ideal. You can also dress up in an elegant jumpsuit or a stylish top-and-skirt ensemble. Experiment with color, prints, and texture.

For Men: The suit and tie remain the norm. You can get a bit more adventurous with colors - navy, grey, or even a subtle pattern.

Smart Casual / Dressy Casual

This kind of dress code is usually found at laid-back or alternative weddings. It's all about feeling smart but relaxed.

For Women: A fashionable maxi or midi dress, a stylish jumpsuit, or a clever trouser-and-blouse outfit is perfect.

For Men: Forgo the tie if you want to! A blazer or sports coat and chinos or smart trousers and a collared shirt is perfect.
