Who: Sienna Miller.

When: Tuesday, June 21.

Where: The Wendy Rowe book launch at the Burberry café in London, England.

What: A long-sleeved, black and gold Burberry wrap dress with contrasting cuffs and black sandals.

Why: Our favorite Burberry girl strikes again — to celebrate Burberry consultant Wendy Rowe's new book, Miller donned an understated, tea-length dress. The gold details and sheer sleeves save the look from Morticia Addams territory, livening it up for a tea party setting.
