Kate Middleton (officially Catherine, Duchess of Cambridge) spent last night at a reception in aid of the National Memorial Arboretum Appeal at St James’s Palace in London. She opted for a gorgeously draped one-shouldered grey Grecian-style gown by Jenny Packham. She did not, however, opt for ‘the Middleton’–her debatable trademark lining of her inner-eyes, which TheGloss has been all over–and her beauty was on point (especially her absurdly glossy hair). So, that’s the substance of this post: Kate Middleton Wears Dress, Looks Fantastic. Do you feel smarter?

No? If not, here’s what Arboretum means (if your Latin is rusty): “A place where trees, shrubs, and herbaceous plants are cultivated for scientific and educational purposes.”

Here’s the full view, with the Duchess alongside the Duke, Prince William:
