The mother-of-two brought a touch of glamour and a whole lotta va-va-voom to the Mothercare VIP Christmas party last night (28 November), held at the brand's Oxford Street store in London.
Myleene - who designs a collection called BabyK for the retailer - stepped out in a form-fitting black frock featuring cute crochet detailing at the waist.
As usual the fashion designer's dress was from her own range for Littlewoods, retailing at £73.
But while we're all for a sophisticated outfit, it was Myleene's beauty look which really caught our eye.
The starlet took a tip from the 50s with gorgeous vintage-inspired curls, plus heaps of lashes and deep burgundy lips.
She kept the rest of her make-up simple, adding a touch of black liquid liner and a low-key peachy hue on her cheeks.
Want to get her look? Here's how:
1. Grab a liquid liner pen (such as Collection Extreme 24hr Felt Tip Liner, £2.99) and draw a line across the top of your upper lashline, flicking it out only a tiny bit at the outer corner.
Next, go back in and make your line slightly thicker at the centre of your lid, just above your pupil. This will make your peepers look bigger and more doll-like.
2. Lashes are an absolute must, and on this occasion the bigger the better! For a mega-watt flutter try Salon System Naturalash in 145, £5.99 from sallyexpress.com.
Before you apply any glue check your lashes fit your eye shape, and if necessary snip a tiny bit off from the outer corners of your falsies. Apply a thin line of glue to the band, then wait a few seconds for it to go tacky before you apply.
Once your lashes are in place, go back over your eyeliner to ensure the band of your falsies blends in seamlessly with your liquid line.
3. For cheeks less is more - go for a neutral coloured cream product like Bourjois Little Round Pot Cream Blush in 01 Nude Velvet, £7.99. The best way to apply cream blushers is with your hands as the warmth from your fingers helps them melt into the skin.
4. Now for the main event - the lips! Start by defining your smackers with a dark red lip pencil, such as KIKO Precision Lip Pencil in 308 Bordeaux, £4.20, before filling in with Rimmel London Kate Moss Lasting Finish Lipstick in 107, £5.49, which is the perfect berry hue.
Christmas party make-up: done. Cheers Myleene!
