Cate Blanchett in Gucci

Personally, I'd go with gold toned jewelry to match the shoes and both jewelry options come in gold tone, FYI. Cate went with silver toned.

Cate Blanchett in Armani Prive

Cate Blanchett looked wonderful in a red Armani Prive suit while in Paris at an Armani Prive show. Get her look for less. The 'less' jacket comes in the same red as the pencil skirt (they are the same brand, material, etc)
