The Lovelace star was prettily ladylike in her collared yellow sun dress, which she toughened up with a black leather jacket and Bottega Veneta basketweave tote.
With those all-black accessories, including her sunnies, we're perplexed as to why she chose nude pumps as footwear. Wouldn't black heels have made more sense?
In fact, we fully expected to see her in those Givenchy sandals she loves so much.
She's a mystery, that Amanda!
