Paris Fashion Week: Balenciaga, Louis Vuitton & Miu Miu

The chicest celebrities in the business rocked the final day of Paris Fashion Week on Wednesday as powerhouse Louis Vuitton and Miuccia Prada's VIP-magnet Miu Miu presented their spring-summer 2016 collections.

But among fashion insiders it was the unexpected decision by Balenciaga to name its new artistic director that drew the most attention.

Here are Wednesday's fashion highlights:

BALENCIAGA'S NEW DESIGNER
Outgoing Alexander Wang had only just said his final catwalk goodbyes in an emotional and intimate show in Paris last week.

Now Kering, the luxury group that owns Balenciaga, made a shock announcement Wednesday that 34-year-old Georgian designer Demna Gvasalia would be replacing him.

It's the third Balenciaga designer in four years for the Parisian house.

The appointment of Gvasalia, head designer of street wear brand Vetements, has raised some eyebrows among fashion insiders as his casual aesthetic appears to be at odds with the established Balenciaga, which was founded in 1919.

LOUIS VUITTON FRONT ROW
"Man from U.N.C.L.E." star and Louis Vuitton ambassador Alicia Vikander turned heads at the Wednesday show in a demure white embroidered top with a frilly ruff, holding court next to powerful U.S. Vogue Editor Anna Wintour and Australian model Miranda Kerr, who sported a multicolored silk blouse and a black leather mini.

They joined Michelle Williams, who appeared in a Peter Pan collar and blond bob, posing for the cameras next to Canadian director Xavier Dolan and French icon Catherine Deneuve.

Elsewhere, American comedian Steve Harvey was in light spirits, laughing and chatting with his wife.

MIU MIU'S GLAM ROCK BOOTS
Oversize sleeves, big coats and show-stopping glam rock boots hit the spot for Prada's little tongue-in-cheek sister brand Miu Miu - a line that's all the rage for edgy pop stars like Miley Cyrus.

The Wednesday show was replete with quirky ideas - dyed fox-tails hanging off belts, sheer lingerie on top of nurses' outfits and padlocks locked to mismatched ankle-tied ribbons.

It was the "more is more" philosophy we've seen before.

But the 39-piece collection was also a showcase of Prada's precise tailoring on some of the best coats of the season. They had contrasting patterns - check, plaid or big ethnic lozenge motifs down shiny boxy leather jackets.

The skirts played with transparency and were set off nicely by the silver-and-gold foil-wrapped auditorium.

MONCLER GAMME ROUGE
Italian designer Giambattista Valli is leading this arm of Moncler in a more floral - well, more Valli - direction. And that's not a bad thing.

The backdrop this season was again a country hillside but more of a spring meadow this time, with yellow-and-blue blooms that made the girly collection appear fresh.

The voluminous jackets associated with this brand are now completely gone, replaced by a new white-dominated aesthetic that borrows from Valli's eponymous ready-to-wear line.

Plays on transparencies in sheer A-line skirts - often embroidered with flower motifs and white laurel crowns- gave this 41-piece display a diaphanous vibe.

White equestrian helmets, large and surreal, injected a sporty vibe alongside swimming suit-style bodysuits and white sneakers.
