Léa Seydoux Wore Three Louis Vuitton Looks at TIFF

Léa Seydoux has been busy at the Toronto International Film Festival, promoting three upcoming films: Alpha Gang, Gentle Monster and The Unknown. And it won’t take you long to notice the theme running through her Louis Vuitton wardrobe.

Alpha Gang Premiere

Léa wore a black Louis Vuitton bustier gown styled with a black belt, opera gloves and satin pumps, and I’m sure your first thought was Old Hollywood glamour.

It’s an easy connection to make, with the silhouette, long gloves and red lip all pointing in that direction. It’s classic glamour, and Léa wears it beautifully.

White-gold and diamond earrings and a bracelet from the Louis Vuitton High Jewelry collection completed her look.

Gentle Monster

The mood completely changed with this black knitted Louis Vuitton dress and short tailored jacket, which, of the three, is probably the least memorable for me.

That said, this appears to have been a more low-key screening rather than a major premiere, which would explain the more relaxed approach. I like the proportions of the cropped jacket, but I’m still missing the glamour of the first look. If Jessica Pearson wore this, I would love it, which tells me everything: it leans more corporate than red carpet.

The Unknown

I’m sure you’ve already guessed the theme by now: all black, everything.

This Louis Vuitton off-the-shoulder jumpsuit was easily my favourite of the three. It feels the most modern, and the silver metal belt breaks up the monochrome while immediately setting it apart from the first look. The neckline and sharp trouser silhouette also make this far more interesting to me than another black dress would have been.

Three films, three black Louis Vuitton looks, but thankfully three different approaches. As good as she looks, I’m hoping for a lot more variety once she takes these films on the road; otherwise, one black Louis Vuitton look is going to start blending into the next.
