As the invites start to arrive, we find ourselves at the crux of the annual style dilemma: how to channel effortless sophistication without turning heads (for all the wrong reasons) at those more formal events. “Nothing that involves a fascinator, firstly” says Katie. There’s a reason we’ve come to associate accessories like these with weddings and race day events – and if you want to avoid looking cliché, best to steer clear of anything too ceremonial.

When it comes to occasion dressing, it’s easy to overlook the importance of being comfortable. While slimline cuts and tight fabrics often present more flattering outfit options, “there's nothing worse than wearing something all day long that's either uncomfortable because it's restrictive, or because it doesn't fit you properly,” says Katie. If you’re attending a full day of celebrations, you’ll need something that you can sit, eat, drink and dance in – without feeling the need to loosen.

“Above all, just feeling like yourself is very, very important” says Katie. “You don’t want to be grimacing at the pictures,” so ensure you find items that nurture any areas you’re conscious about. For example, “older women often don't like showing their arms, but a little crop jacket can help with that.” Not only does it work as a modest option for a formal event but importantly, “in the evening, it can come off” when the cameras are packed away and the more relaxed receptions begin.

“For women, you don't always have to be wearing a skirt or a dress. Wide-legged, loose trousers with a cropped tailored jacket as an occasionwear option looks fantastic.” Similarly for men, don’t feel like you should always opt for a traditional two-piece suit for those more formal events. Especially on days when the weather permits, “a good, tailored city short, pleat or flat fronted will update just right,” says Katie.

Small yet impactful, accessories have the ability to take an occasionwear look from high fashion to major faux pas. “I can't think of any other style but a clutch bag that doesn't spoil the line of anything you're wearing,” says Katie. And when it comes to hats and jewellery, typically less is more. Pare back statement outfits with elegant metals and accessories. Or dial up understated glamour with small clusters of sparkle, pearls or feathers for an opulent finish.
