The fashion formula experts say will make any outfit sing: Our editors reveal the three steps that make an outfit flattering and anti-ageing… and show how to do it

Christmas parties and events are tricky, sartorially speaking.

You want to have a little fun with your look, but equally you don’t want to be the only person wearing head-to-toe sequins, when the rest of the room has gone for smart black dresses with a hint of sparkle.

Thankfully, there’s a foolproof formula insiders use to make an impact without ever looking overdressed.

Whether it’s work drinks at the pub or a chic cocktail party, you’ll always look the part (and you won’t have to buy anything new… unless you want to, of course).

The secret? Build your outfit from three key items: something that makes a statement, something formal, and something casual. You can see our examples below, with the formula spelled out beneath each image.

The casual element is the most important here, giving off a subtle ‘cool girl’ vibe that balances out your look. Think of a dazzling metallic jacket paired with a smart skirt and comfy loafers. Or a standout sequin skirt, plus a crisp white shirt, given casual appeal with a cosy, fleecy jacket.

Of course, this trick won’t do for every occasion. If you’ve got a black-tie event calling or a wedding on the horizon, then making an effort is not only respectful but de rigueur. But for everything else, you can’t go wrong when you dress down to dress up…

Metallic dazzle

Metallic jacket + Smart leather skirt + Flats

This jacket has all the oomph you need at a party – it’s a major statement.

Add a smart leather skirt for a formal, polished note – then finish with easy loafers and you’re ready to dance the night away.

Bold bling

Bobble necklace + Velvet trousers + Casual jumper

The oldest styling trick in the book is to add a statement accessory to a simple look.

The bobble necklace by Essentiel Antwerp, or something similar like the COS chunky beaded necklace, adds all the interest you need to liven up your outfit. Swap for chandelier earrings or a chunky cocktail ring if you prefer.

Scarlet showstopper

Cocktail dress + Smart coat + Flat boots

Flat shoes or boots make things so much simpler. Pair a fabulous dress with flats and even add a classic coat – which will work over so many party looks.

Denim and fabulous feathers

Sequin shirt + Cool jeans + Slingbacks

Keeping things practical is where it’s at this Christmas. And whether it’s a boot or barrel, flares or fitted, denim delivers, whatever the occasion.

Christmas jumpers are cosy but only get a handful of wears in December. Switch it up with a dazzling sequin top, like this one from Zara.

Stunning sequins

Crisp shirt + Sequin skirt + Cosy jacket

A shiny addition always feels right at this time of year, but looking like a Christmas tree is just trying too hard.

If you go for this sequin skirt, keep the rest of your outfit easy by teaming it with a crisp white shirt and a neutral, casual jacket to balance out your look. Dial down the dazzle, it’s still there, but it doesn’t need to be overdone…

Big energy boots

Jumper dress + Smart belt + Metallic boots

Wearing next to nothing and shivering at the bus stop is a thing of the past. Cosy up in a jumper dress and you could even layer thermals underneath, too.

This dress is smart enough for the office, too. Add a formal belt and statement boots for all the oomph you need at a party.
