By this time of year you’ve probably mastered your warm-weather-wedding outfit, but what do you wear as a wedding guest when the weather drops?

Crisp days and darker evenings mean autumn weddings are well suited to heavier fabrics and richer colours. A three-piece tweed suit has no place at a summer wedding, but it’ll really come into its own in a chilly church in October.

Pack your pastel floral accessories away until spring and try one of these three stylish ways to dress for an autumn wedding:

Part of the joy in autumn months is being able to layer up in thicker fabrics and, helpfully, textured Donegal suits continue to be a stylish choice this season. These rustic Moss London Donegal suits in grey, brown or blue are particularly suited to a semi-formal wedding in a traditional country manor, but they’ll look just as great for guests going to more urban venues.

Donegal fabrics are generally woven in wintry tones with subtle flecks of colour, and one way to make a feature of on this is by teaming your Donegal 2-piece with a waistcoat in a contrasting colour – all three Moss London suits seen above will look great styled in any combination.

A knitted tie will continue the wintry texture theme, but our new Moss London knitted bow-ties – available in several autumnal shades – will add a particularly charming touch to a wedding guest outfit. At this point, some of you will be most comfortable anchoring the look in a textured white shirt, but for those of you willing to take it a step further, a gingham shirt in a sleek slim fit will add a final rustic flourish.

The easiest way to take your wedding guest outfit into more autumnal territory is by paying attention to its texture. If the Donegal looks above are too ‘country’ for your tastes, you’ll be glad to hear that surface texture is a key trend for the season and adds a wintry feel to formal fabrics in a much more subtle way.

This navy speckled Moss 1851 suit gets its interesting salt-and-pepper texture from an intricate cross-weave cloth, while this Moss London blue scratch suit also features a subtle white surface texture but is cut from our slim fit block and features patch pockets for a nearter, more minimal look. If the wedding invitation requests you dress a little more formally, this light blue speckled suit, also by Moss London, is made from Italian Comero fabric with occasion-worthy wide peak lapels.

Let your textured suit do most of the talking and pair it with a luxe white shirt and berry-hued accessories. This Moss London skinny tie comes in a rich navy and wine floral pattern, which is a great autumnal take on traditional flowery wedding accessories. Tie it in a tight four-in-hand knot to complement a sophisticated spread collar shirt, such as on this white DKNY one. It’s made from a smooth, sateen fabric that’s elegant for a wedding and also features formal double cuffs, so cufflinks are essential. We suggest playing up to the surface texture theme with these striking marble-effect cufflinks.

For some of us, buying a whole new outfit for a one-off wedding is not the most budget-friendly option. If that’s the case, investing your hard-earned cash in something blue will keep you in the black, at least in terms of longevity and wear.

There are countless occasions when a blue suit will see you right, from smart office-wear to getting dressed up for a wedding – just make sure you pick a timeless tailored fit in a versatile blue, such as this one by Ted Baker or this superfine 100% wool Moss 1851 suit . Alternatively, if the wedding you’re going to is a bit more relaxed, you could opt for a smart navy jacket – this one’s softer shoulders and modern patch pockets lend it a more casual appearance that would work for an evening reception or less formal dress code.

The key to making sure any blue suit is wedding-appropriate is in the styling. The same goes for if you already own a blue suit for work: some simple styling tricks will take it from weekday to wedding with ease.

Pastel floral accessories will always say ‘wedding’, but for a more autumnal approach, try teaming your blue three-piece with this printed shirt. Its falling-leaves pattern is a romantic nod to autumn days, but its graphic style keeps things modern. Finish off the look with some sharp monk shoes in a tan brown and a richly toned pocket square – this one’s regal purple shade is on-trend while its geo pattern will play nicely off the one on your shirt.
