Looking at the images on Getty, one positive thing about Alexa's outfit is that she looks like Alexa!
All the other female celebrities seem to have blended into some kind of generic mish-mash of never ending red fabric and heaving bosoms. The second I saw the thumbnails of the photos, I could spot her a mile out.
To me, this is why Alexa's style works. She doesn't go by the book. Here she looks under-dressed when surrounded by all the gloss and glamour, but I like that. She looks like she's being true to her own tastes. I'd be kinda shocked if she'd turned up all guns blazing. The hair, the make up, the shapes, the fabrics - it's all very Chung.
