Wedding season is officially upon us: you've accepted the invitations and marked the dates in your diary. Now, all that's left to do is decide what to wear.

These days, a top hat and tails are no longer de rigueur: dress codes have relaxed and guests have more freedom to select outfits that they feel comfortable in. Summer weddings in particular often call for smart or smart casual looks, rather than head-to-toe formal attire. The heat certainly is not conducive to sporting heavy woollen three-piece suits and flannel shirts, particularly if it's a destination wedding at an exotic beachfront location. Instead, opt for a suit or tailored separates in lightweight and breathable fabrics like linen, seersucker or organic cotton.

The best part about dressing for a summer wedding is that it presents the perfect opportunity to have a bit of fun and experiment with colour. Now is not the time for grey and black. Instead, go for tailoring in light, neutral or pastel shades, and branch out with your shirting: hues like sage green or pale pink will work well. During the warmer months, consider contrasting your separates, opting for a lighter shade for your trousers and a slightly darker colour for your jacket.

A pair of smart shoes is essential, but don't feel restricted to lace-up Oxfords or derbies. Loafers or brogues will suit just about any venue, while boat shoes are ideal for more casual beach weddings. Accessorise with a coloured knitted tie or silk pocket square, if you so wish, and certainly don't forget a pair of sunglasses: squinting through the ceremony is never a good look.
