Jessica Biels sunglasses

I think they're definitely Tom Ford and they look like the Lydia's but I'm not sure if they're a bit bigger than the Lydia... here's a link with some more photos.

They look great on her so I'm definitely interested in finding out what they are.

Aren't they great? All the pics I see of Lydia look huge and these not so much. I will need to go and try them in in person to see if they are indeed the Lydias.

Thanks for all your help ladies!
