Former chief of protocol Capricia Marshall traded her usual impeccable designer workwear Tuesday night for a far more downscale look: an old-school striped bowling shirt and retro bowling shoes.

What prompted the drastic makeover? Marshall and other big names, such as CNN’s Wolf Blitzer, former Department of Health and Human Services Head Kathleen Sebelius and comedian Donnell Rawlings, were suited up for competition at a Hope for Henry charity bowling event at Georgetown’s Pinstripes bowling alley.

“There are a lot of black tie events in Washington, so I figured the last thing they need is another one,” said United Arab Emirates Ambassador to the United States Yousef Al Otaiba, whose wife Abeer is the event’s honorary chair.

In addition to the action in the lanes, the evening featured a silent auction with items ranging from a guitar signed by Australian teen heartthrob/singer Cody Simpson to a four-restaurant tasting by local celebrity chef Jose Andres.

The cocktail hour had a relaxed vibe — faux-grass turf was underfoot and Major Lazer’s “Lean On” blasted from the speakers.

“I love this event because it is very low-key,” said Georgetown Cupcake co-owner Sophie Kallinis Berman, who works with Hope for Henry with her sister and business partner, Katherine Kallinis Berman. “It’s different from a typical D.C. fundraiser. Everyone can just have fun and relax.”

Is the ambassador the king pin in the lanes that he is in the diplomatic world?

“Oh my God no, and you’re about to find out.”
