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 sartorially tricky.

You want to have a little fun with your look, but you also don’t want to be the only one wearing head-to-toe sequins while the rest of the room opts for smart black dresses with a hint of glitter.

Luckily, there’s a foolproof formula that insiders use to impress without ever looking overdressed.

Whether it’s a work drink in the pub or a chic cocktail party, you always look good (and you don’t have to buy anything new… unless you want to of course).

The secret? Create 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 described below each image.

The casual element is most important here and exudes a subtle ‘cool girl’ vibe that balances your look. Think of a dazzling metallic jacket combined with a neat skirt and comfortable loafers. Or a striking skirt with sequins, plus a crisp white shirt, which gets a casual look with a cozy, woolly jacket.

Of course, this trick isn’t suitable for every occasion. If you have a black-tie event or a wedding on the horizon, making an effort is not only respectful, but also de rigueur. But for everything else, you can’t go wrong with dressing up to get dressed…

Metallic glare

Metallic jacket + Neat leather skirt + Flats

Sofia Irina leather skirt, $489

NEXT Metallic Blazer, $229; Sofia Irina leather skirt, $489; and Sandler Flat Loafers $169.95

This jacket has all the look you need at a party: it makes a big statement.

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

Bold bling

Bobble necklace + Velvet trousers + Casual sweater

Belle & Bloom velvet pants, $129.95

COS chunky bead necklace, $99

Belle & Bloom Velvet Trousers, $129.95; and COS chunky bead necklace, $99

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

Essentiel Antwerp’s bobble necklace, or something similar like the chunky beaded COS necklace, will add all the interest you need to brighten up your outfit. Swap for chandelier earrings or a chunky cocktail ring if you prefer.

Scarlet showstopper

Cocktail dress + Dress coat + Flat boots

Tussah Dress, $169.95

Belle & Bloom Flats, $149.95

Tussah Dress, $169.95; and Belle & Bloom flats, $149.95

Flats or boots make it all so much easier. Pair a fabulous dress with flats and even add a classic coat – which will suit so many party looks.

Denim and fantastic feathers

Sequin shirt + Cool jeans + Slingbacks

Zara Sequin Top, $75.95

Assembly Label Jeans, $120

Zara Sequin Top, $75.95; and Assembly Label jeans, $120

Staying practical is what this Christmas is all about. And whether it’s a boot or a round shoe, flared or fitted, denim delivers, whatever the occasion.

Christmas sweaters are cozy, but are only worn a handful of times in December. Switch it up with a dazzling sequin top, like this one from Zara.

Beautiful sequins

Fresh shirt + skirt with sequins + cozy jacket

Seed Heritage Sequin Skirt, $69.95

CAMIXA white shirt, $79.90

Seed Heritage Sequin Skirt, $69.95; and CAMIXA white shirt, $79.90

A shiny addition always feels good this time of year, but looking like a Christmas tree is just too difficult.

If you go for this sequin skirt, you can keep the rest of your outfit simple by pairing it with a crisp white shirt and a neutral, casual jacket to balance out your look. Turn the glare down, it’s still there, but it doesn’t have to be excessive…

Great energy boots

Sweater dress + Neat belt + Metallic boots

NEXT dress, $71

Princess Highway Metallic Boots, $43.60

NEXT dress, $71; and metallic Princess Highway boots, $43.60

Wearing next to nothing and shivering at the bus stop is a thing of the past. Feel comfortable in a sweater dress and you can even wear thermals underneath.

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