Show some skin in a cut out dress by Sass & Bide

With party season almost upon us (how did that happen?) it's time to find that perfect dress to see you through the countless events in the social calendar.

And of course black is the classic choice for such things and you really can't go wrong so why not give that LBD of yours an update for AW15? Kate Beckinsale is providing ample inspiration in this fantastic number by Sass & Bide.

The Australian label is a go-to for stylish celebrities like Whitney Port, Eva Longoria, Pixie Lott and Taylor Swift so you know you're in safe hands when it comes to a head turning look.

Kate's dress is from the brand's Resort 2016 collection and we love the glittering knitted skirt and the sexy cut outs at the waist. Sadly it's not available to buy just yet but click (right) to check out the current line at Shopbop.

Or recreate Kate's party style with our edit of similar cut out LBDs below.

Kate showed off her svelte figure in an understated yet effective black dress, showing off her toned arms and her trim waistline through smart little cut-out details on the side.

The snug pencil skirt of the black dress was decorated with a detailed shiny pattern, glowing in a shimmering pewter shade, and elevating the look from a simple LBD.

Her slender physique had never looked so good, the form-fitting design showing off every inch of every curve she's the proud owner of.

Keeping it classy, Kate teamed the gorgeous garment with a pair of barely-there strappy black sandal heels, and no accessories but for a tiny pair of earrings.

The Underworld actress' hair was glossier than ever, her brunette mane teased into elegant curls, sitting on her shoulder and parted neatly at the side.

And she more than proved she has her posing stance well and truly nailed, as she stood for photos inside the decadent abode, pouting accordingly and smouldering for the cameras.

She also joined Brit comic Jimmy Carr and his wife Karoline Copping for a snap. 

The star - who is married to director Len Wiseman - has seemingly been in her homeland for a couple of weeks, after being seen arriving from Los Angeles in the last week of September.

She lives and works in Los Angeles with her husband and her daughter from a previous relationship.

Also at the star-studded event, held during the annual BFI London Film Festival, was the flawless Cate Blanchett, fresh from her turn on the red carpet at the Carol premiere earlier in the evening.

The 46-year-old donned a unique white layered dress, complete with gaping cut-outs over her shapely torso, a high neck and large bell-shaped sleeves, and a black bow to tie it together at the front.

It was certainly a tricky garment to wear - not one for the faint of fashion heart - but the slender stunner pulled it off with aplomb.

Accompanying her was co-star and fellow red carpet-walker from earlier in the day, Rooney Mara, who had kept on her premiere dress - a nude, sheer gown, that showed off her lovely legs underneath.

But inside the party, the 30-year-old actress kept her covetable, chic beige coat draped over her shoulders, clearly feeling the early British autumn chill despite being safely behind closed doors.

Actress Cressida Bonas - Prince Harry's famous ex-girlfriend - has been doing her bit on the London social scene of late, and made her appearance known on Wednesday at the Ambassador's reception.

The pretty 26-year-old opted for a pair of high-waisted black satin trousers with a tapered ankle, and a bright blue blouse with a high collar and slim tie detail.

Adding a feminine touch to her separates, her blonde hair was piled up into a sweet updo, tied up with a black ribbon.

Other famous faces at the swish bash included Jeremy Piven, legendary actor Patrick Stewart and his wife Sunny Ozell, actor James Purefoy and his wife Jessica Adams, the lovely Gugu Mbatha-Raw and Joan Collins, who was joined by husband Percy Gibson, and directors Ridley Scott and Tom Hooper. 

Meanwhile, with two films in post-production, Kate looks to be taking a break before she reprises her role as vampire warrior Selene in Underworld: Next Generation. 

Following on from the last installment in the franchise three years ago, the films producer and her husband Len recently revealed the film will shed yet more light on the alternative universe the films are set in.

He told IGN: 'There's kind of more of a spin-off of some of the characters like we did with Rise of the Lycans and then another film is also being developed in the works with Kate possibly as well, and then there's a television series as well.'

'It's kind of expanding that universe in many ways.'

And while the plotline of the film is not known at this point, the fifth outing of the popular horror/action franchise is set to hit cinemas in October 2016.
