A FASHIONABLE Noel demands a versatile wardrobe. When else in the year are you likely to change from snowman jumper to sequin dress on the same day?

But you don't need to plan entire outfit changes for the December festivities; a few simple tweaks can take a risque get-up to auntie appropriate in no time.

Switch effortlessly from desk to dancefloor, or PJs to glad rags, with casualwear upgrade trickery. Look to Santa Claus for inspiration - a statement black belt completes that classic red suit!

Try these transition wonders that work around the festive clock.

OFFICE PARTY

Streamers and shots might start flowing at 7pm, but you have a full working day at your desk first. The solution? "Transform from working girl to glamour puss by choosing your daytime pieces well in the first place," advises Annebelle van Tongeren, author of Dress Like A Star.

Pick out your favourite party frock, or glam top and separates, and turn down the glamour for daytime with a fluffy sweater layered over the top. Avoid jumpers that shed on to your dress underneath and ruin the effect when you unveil.

"The use of colour can be powerful too," suggests van Tongeren. "Pick the hue up in your shoes as well and you've changed your working look entirely."

HAPPY HOLIDAYS

Feet up by the fire? Not with last-minute presents to buy, then delivery rounds to get through and relatives to see.

Straight or skinny jeans will take you from day to night but team with sparkly flat shoes - perfect for pounding pavements, and looking pretty for grandma. If you have a big family gathering, change into a gilt-edged sequin or metallic top to impress your relatives.

"The addition of metallics is an easy solution for anything revolving around denim, as it gives a glamorous night-time edge to the versatility of jeans," says van Tongeren.

"You could also add luxe textures, such as velvet and satin trims, to pieces that will work with denim for evening."

CHRISTMAS DAY

It's the ultimate lazy day but you can still be slouchy and chic on December 25, with some tactical layering.

"Use more feminine fabrics for the pieces underneath," advises van Tongeren. "Silk camis hiding under big knits will transform your look from day to night in seconds."

For present opening, opt for patterned, silky pyjama trousers for a glam take on frumpy flannel PJs.

Team with a cami underneath a novelty festive jumper, so you can take your look from daytime Christmas table to after-dark turkey canapes - you shouldn't be cold with the fire roaring and sherry-induced glow.

NEW YEAR'S EVE

In an ideal world, we would all have hours to perfect our last party look of 2013. In the real world, though, it might be more like 15 minutes flat.

If you've been on the go all day, stick to a trusty LBD for a fail-safe foundation that you can build your look around, with some well-chosen accessories and outerwear that wows.

"Dresses are simple to transform," assures van Tongeren. "The change of subtle day jewellery to something more sparkly, the addition of a killer coat, and some glamorous high heels replacing your sensible shoes and you are ready to go."

Intensify your make-up with a bold lip or touch of shimmer and finish off your outfit with some arm candy, in the form of a bling watch for the big New Year countdown.
