After months of designing and making a collection, it's hardly surprising that certain elements might rub off on a designer, their own style either influenced by what they've just created or an influence upon it. Either way, it makes sense that you'd see the designer's doppleganger taking a turn down the catwalk. Here, we round up "The Dopple Gang", as it were, the catwalk looks and the designer outfits that make you take a second glance. Are you seeing double? Yes!
1. MARC JACOBS
Seventies by way of the Nineties, or was it the other way around? Regardless there was a distinct hip-hop feel to Jacobs' latest collection, medallions making for the accessory du jour, sported by the designer himself at the end of the show also.
2. EUDON CHOI
Lean lines provided the basis of London-based designer Eudon Choi's collection - lots of looks with high necks. Choi was clearly inspired by his own wardrobe choices, as his own bow outfit shows.
Rihanna went back to school for this season's Fenty offering with Puma. The uniform? Hoodies, hot pants and plenty of sports-streetwear, all the hallmarks of the lady herself.
4. SONIA RYKIEL
Stripes are a signature of the Parisian house so it's no wonder that they turned up among the collection and as the closing look of choice by current creative director, Julie de Liban.
5. YOHJI YAMAMOTO
The master of avant-garde tailoring, a layered look and a penchant for dark colours, the man himself always dresses the part, this time topping it off with a tilted hat just like the last series of looks.
6. NEITH NYER
Who doesn't love an aviator jacket? Such a good idea did they seem on the catwalk that the designer made his finale appearance in one, too.
7. STELLA JEAN
Stella Jean loves a dirndl skirt, her aesthetic a far more crafty and artisanal approach than we so often see in Milan. So it was a no-brainer that she too would step out in one to make a bow.
Of course Donatella is her own poster girl when it comes to the Versace woman. There simply is no one else.
9. VICTORIA BECKHAM
Likewise, VB. Here rocking a casual-smart ensemble like this one on her catwalk.
10. ANNA SUI
Queen of boho glam and dress-up fun Anna Sui's collections are a walking embodiment of the designer's own style. They key component? A shaggy coat.
In London, Roksanda's own art-inspired aesthetic has become her USP.
12. CAROLINA HERRERA
Prim, proper, elegant and Park Avenue chic, that's what Herrera is known for - and what better outfit conveys that than a crisp white shirt and elegant skirt combination?
13. PRABAL GURUNG
Politics and the despairing state of the world today was a strong subject on the catwalks this season, kick-started in New York by Prabal Gurung who, during a walkthrough, sent out a series of T-shirts with slogans such as "I am an Immigrant" and "Break Down Walls" on them. He, too, wore one to make his point.

14. PUBLIC SCHOOL
Over at Public School, designers Dao-Yi and Maxwell Osborne reimagined Donald Trump's "Make America Great Again" campaign slogan on caps as "Make America New York" - sported by the models and themselves as they took their finale bow.
