Sienna Miller and Kevin Costner

This photo just makes me laugh. He looks so weird lurking back there. I regret to note that his colorist surely did their best but this hair looks kooky. It's giving Shein I'm Just Ken. (Sienna's blonde, on the other hand, looks PERFECT.)

Sienna Miller in Chloe

This is a dress that works only on VERY specific people. I think Sienna Miller is one of those people; this aesthetic really works for her. Other folks would look like they're walking around in Granny's dusty window treatments, but she carries it very well.

Sienna Miller, Marlowe Sturridge and Oli Green

Aw, this is Sienna's eldest daughter. She looks SO cute; her dress is perfect. (She's 11.)

Ella Hunt in Fendi

I am generally not a huge fan of Fendi's work in the sphere of clothing -- accessories are, obviously, more their forte -- but this is very ethereal and pretty on her.

Ella Hunt in Fendi

And the train is lovely.

Isabelle Fuhrman

...honestly, I love it. The texture is so pretty.

Wasé Chief

She looks great, although I might have branched out from white in the accessories and jewelry?.

Julianne Moore

This color is always great on her and she looks good here BUT! I also suspect none of us will remember this in 48 hours.

Michelle Yeoh in Bottega Veneta

Meanwhile, I don't actively LIKE this -- she looks like she's wearing one of their deconstructed bags? -- but it IS memorable?

Georgia MacPhail

She's young -- though the internet has not clarified for me HOW young? -- and this feels just right, although I think it would have been potentially better without the train.

Abbey Lee Kershaw

This is objectively pretty but also somehow leaves me cold? Perplexing.

Jena Malone

Princess Leia is back and she looks AMAZING.

Philippine Leroy-Beaulieu

This isn't my favorite look on THE QUEEN of Emily in Paris but she is, as mentioned, a queen and so who cares.

Marina Ruy Barbosa in Miss Sohee

...truly, I think this is fabulous on her. It's A LOT but also she's at Cannes. CANNES is a lot.

Lady Victoria Hervey

On the other hand, for me this is Too Much. It's like Sparkle Missoni Does Marvel.

Im Yoon-ah

PALATE CLEANSER.

Hofit Golan

I shouldn't like this dress...but I do. Shrug. We humans are a complex animal.

Kim Hnizdo

This is pretty. Cannes has been VERY red this year.

Candice Swanepoel

I was more excited when I thought her collar came WAY up. Then I realized that was just an optical illusion created by a man behind her.

Toni Garrn

This is, unfortunately, one of the worst deployments of illusion netting I've seen in a long time. This whole thing is just a light mess.

Alexa Chung

Chic!

Mary Leest

Also chic!

Anja Rubik

Conceptually, I love it. In practice, this might have needed another pass.

Isabelle Huppert in Balenciaga

This is the most glamorous bathrobe in all of France.

Claire Holt

She looks good here, although I'd bet money this dress was made for a taller person and not altered to fit her.

Diipa Khosla

DRAMATIC FINISH.

Sienna Miller AND Kevin Costner Are Blonde for All the "Horizon" Events in Cannes

EVERYONE came to this premiere.
