While cheering for fellow Brit Andy Murray as he played Grigor Dimitrov, Middleton, 32, wore the breezy eyelet dress that she debuted during the royal tour of Australia in April. The Zimmermann Roamer Day Dress, which didn't become available until June, costs $520 and is available in very limited quantities on Zimmermannwear.com.
However, fans of the eyelet dress are in luck as Zimmermann expanded its Roamer collection with a halter dress that's available for pre-order on Revolveclothing.com for $360.
The tennis match offers a brief break from a packed week of royal duties. On Monday, the Duke and Duchess attended an annual conference in London of a charity that they patron. And on Tuesday, July 1, Middleton visited a local school to check out a special program supporting children affected by parental substance abuse that she helped launch in 2013. The Duchess wore a bright pink Goat dress with a silver circle belt.
