Olivia Palermo goes back to basics as she opts for a low-key black coat and leather trousers at the Barbara Bui PFW show

She's a bona fide front row fashionista and is a leading member of the style elite.

But Olivia Palermo decided to keep things simple as she attended the Barbara Bui a/w 2017 show during Paris Fashion Week on Thursday.

Showing off her style prowess, the socialite, 30, opted for a classic all-black ensemble, adding some quirky touches to her outfit to ensure she would still make an impression.

Slipping her long legs into a pair of black leather trousers, the socialite combined both style and practicality - showing off her toned pins whilst remaining warm in the chilly Parisian climes.

Layering up, she donned a black pussybow blouse, leaving her neck-tie loose and trailing past a military style coat that she flung over her shoulders. 

Adding some height to her modelesque frame, she wore a pair of fringed black ankle boots as she teetered towards the front row.

Injecting a subtle splash of colour to her ensemble she held a pop art style clutch, whilst she dangled a pair of sunglasses from her red manicured fingers.

Wearing her honey coloured tresses in loose waves, she parted her glossy locks in a centre parting, the loose waves tumbling past her shoulders and framing her face. 

Accentuating her petite features, the American star wore a sweep of rosy blusher on her defined cheekbones, whilst illuminating her stunning complexion with carefully applied highlighting powder.

Making her way around the French capital, the blonde beauty also made an appearance at the Balmain show at Hôtel Potocki, uncharacteristically opting to wear the same outfit for both shows. 

Clearly rushed off her feet during the show, Olivia then headed to her room to relax, and was greeted with a little treat from the staff.

Clearly a regular guest at the luxury hotel, the dedicated workers had made a note of the star's recent birthday on Sunday, and pulled out all the stops to ensure she could celebrate in style.

Posting a snap of her room on Instagram, Olivia was seen surrounded by bunches of flowers and clutching a balloon whilst a bottle of bubbly rested on the table. 

Still in her outfit from earlier - but swapping her heels for patterned black loafers - Olivia seemed overwhelmed with the gifts, beaming broadly down the lens. 

'What a welcome!' she wrote. 'There's a reason @leroyalmonceau is my favorite hotel in Paris. Merci beaucoup for my birthday surprises! #LuckyGirl'
