Megastars have groomed, strutted and posed on acres of red carpet all year long - but who wore the dresses that really stood out?
We've whittled down the year's most outstanding gowns to an 80-strong high fashion spectacular; including Naomi Watts in canary yellow Gucci at the Golden Globes in January, Beyonce in glittering Givenchy at the Met Gala in April, through to Daisy Ridley in Star Wars-themed Roland Mouret for the film's London premiere in December.
This is Stylist's definitive edit of the 80 most outstanding dresses of 2015.
January: Monday 5 January is possibly the worst date to throw a party, but Jennifer Lawrence RSVP'd yes to the 26th PGA Awards and she's damn well going to get dressed up.
She's boldly kicking off January - and a spectacular year of red carpet dresses - in plunging, jewel-encrusted Prada. A thigh-split too? Why not? 2015 is going to be a good year.
January: Liquid bronze becomes a viable party dress colour, thanks to Jessica Chastain and her shimmering Atelier Versace at the Golden Globes.
January: Stealing. The. Show.
Three cheers for canary yellow Gucci and bejewelled snaking asp necklaces.
January: The man on the far left - that was us when we saw this Miu Miu frock working so hard on Sienna Miller.
January: Well, if anyone's going to bring back opera gloves and shoulder veils, it's a Christian Dior-clad Amal Clooney.
January: Anna Kendrick, we love you no matter what you wear, but in this fairytale Monique Lhullier, you are really spoiling us.

Steely pose and big bun, Kate Beckinsale's own.

Then think "Obvs."
She's giving it everything in Versace, at the Atelier Versace show.
January: It's a bold claim, but we're going for it: This is our favourite dress on Jennifer Aniston. Ever.
It's vintage Galliano for the SAGs.
February: What? This old thing? It's just an ombre teal Elie Saab I had in the back of the wardrobe.
Superhero meets Disney princess for Taylor Swift at the Grammys.
February: Not only is this Giambattista Valli frock the outfit equivalent of candyfloss, it took up three seats at the Grammys.
February: Plastic fence netting, that most underused of dress materials, is a stirring reminder of how one frock can give a rising star a leg up, also at the Grammys.
February: Thank you, brave designer Atsuko Kudo Dusty, for this special, rubbery gift of a dress that has been a year-long source of wonder.
How will Kim Kardashian top it in 2016?
February: Part velvet, part crepe, complete fabulousness - it's vampy Tom Ford for the Baftas.
February: Like crossing a Klimt painting with a game of Tetris.
Cate is playing this Givenchy gown well at the Cinderella premiere in Berlin.
February: Lilac is almost as underused as dresses with pockets, we say.
Gugu Mbatha-Raw's Prada gown is brightening up the sponsored backdrop at the Baftas.

February: Full marks for pairing this delicate beaded chartreuse gown with a punchy coral lip, Emma Stone.
February: Stunning, yes, but is this a dress worth doing time for?
One thief thought so. Lupita's $150,000, 6,000-strong pearl Calvin Klein gown was stolen from her hotel shortly after she wore it to the Oscars.
It was later dumped by a man who told TMZ the pearls are "fake".
