Paris Fashion Week Haute Couture AW15: all the best celebrity fashion

Fresh from her glamourous appearance at Lancome's 80th birthday, Lupita Nyong'o started the day in style at Maison Margiela's AW15 show.

It was all about the bodycon for Jessica Alba at Tory Burch's Paris store opening.

We love the colour of this deep, burgundy dress on the beautiful Glee actress Dianna Agron.

We love K-Stew's button-up velvet suit - comfy AND cool

Julianne Moore looked elegant and cool in her long-sleeved velvet maxi.

Rita Ora went full throttle for her appearance at Karl Lagerfeld's Chanel haute couture show in a plunging, silky silver suit.

HOW cute is Rosie HW's checked mini? The star wore the dress to watch Christian Dior's AW15 Haute Couture show.

Lupita did what she does best (when it comes to getting dressed) at the Dior AW15 show by wearing a bright, bold and beautiful dress for the occasion.

We love Emily Blunt's smart and chic white summer dress.

The winner of the 'most interesting outfit' award at this year's Haute Couture Fashion Week goes to the very stylish Olivia Palermo.

It was a black, sheer crochet kind of occasion for Naomi Campbell.

RHW went for a shirt-meets-shorts-meets-half-skirt-dress thing at the Vogue Paris Foundation party on Monday.

Adding a splash of colour to the Vogue party proceedings was the beautiful Irina Shayk in a scarlet mini dress.

Jessica Alba paired her printed mini with some seriously cool over-the-knee boots at the Giambattista Valli show.
