It’s a good weekend to celebrate in D.C., with festivals and parties all about the ’90s, ice cream, fashion, and local food.

FRIDAY, SEPTEMBER 21

SHIRLEY IT HASN’T BEEN 80 YEARS ALREADY? In its 80th year, the Old Greenbelt Theatre in Prince George’s County wants to look just as good as it did in year one. They mean that literally: Friday’s birthday celebration will recreate the theater’s first night in business in 1938, complete with a showing of the Shirley Temple movie Little Miss Broadway. There will also be cake and Shirley Temple drinks, of course. (Old Greenbelt Theatre, 7 p.m., $19.38)

SO, YOU WANNA GO TO A REAL PARTY? For its latest after-hours museum bash, Brightest Young Things has taken a page from Adele’s book and gone with a Titanic (the movie) theme, to honor the exhibit at the National Geographic Museum about the Titanic (the ship). Celebrate only the first half of the movie, we guess (?) at this all-90s party, featuring performances from White Ford Bronco, talks from National Geographic explorers, and more revelry. (National Geographic Museum, 8 p.m.-midnight, $25-$30)

BUY ME SOME SCHNITZEL AND BRATWURST: You’ve got only one more week to catch a home game at Nationals Park, so you might as well make it a party. Friday’s game against the Mets is also Oktoberfest night, which includes performances from Bavarian and Austrian dancers in Centerfield Plaza before the game, along with German-ish foods being sold at concession stands. Nothing says “play ball!” like bratwurst, pork schnitzel, and giant pretzels, right? (Nationals Park, 7:05 p.m., $10-$95)

DANCE DANCE EVOLUTION: Before Julie Kent took the reins at The Washington Ballet in 2016, she was the longest-dancing ballerina at the American Ballet Theater, where she danced alongside Misty Copeland. She’ll speak about her extensive history in dance, and how she’s shaping The Washington Ballet in a field dominated by men, in a free panel discussion at American University. (Katzen Arts Center at American University, 7:30 p.m.-9:30 p.m., FREE)

MORE: Weirdos For Life (Bier Baron, 9 p.m., $15-$20), Elton John: Farewell Yellow Brick Road (Capital One Arena, 8 p.m., $199-$249+), MarketSW (4th and M St SW, 4 p.m.-10 p.m., free entry)

SATURDAY, SEPTEMBER 22

WE ALL SCREAM FOR THE ARTS SCENE: After being delayed a week by Hurricane Florence, the King Street Art Festival is officially on this weekend, offering up lots ($15 million worth!) of locally-made craft art. The weekend’s best event, though, is its annual ice cream bowl fundraiser. Purchase a ceramic bowl, handmade by Alexandria artists, for $15, and get a scoop of ice cream. All proceeds go to The Art League, offering classes and exhibit space in Alexandria. (King and N. Fairfax Streets, Alexandria, 10 a.m.-4 p.m.; also Sunday 11 a.m.-4 p.m., free entry)

THE CAT’S MEOW: “Realm of the Jaguar” is not the subtitle of a lost Harry Potter book, but the title of a dance event at the National Museum of the American Indian on Saturday and Sunday. As part of National Hispanic Heritage Month, NMAI will celebrate the jaguar, an animal found in ancient imagery, with a series of traditional dances based in Bolivia, Mexico, and Guatemala. (National Museum of the American Indian, 10 a.m.-5 p.m. Saturday and Sunday, FREE)

AWFULLY FUNNY: Because apparently white supremacists need something to read, too, there’s the long but awful catalog of “race war” fiction: highly racist books that imagine dystopian futures where only the neo Nazis save the day (Stay with us here). DC Arts Center’s latest world-premiere play, The Klunch: How to Win a Race War, satirizes these tomes in a three-hour comedy of song and dance that spans the antebellum south to a liberal dystopian future. (DC Arts Center, through Oct. 20, various times, $20-$25)

SHE WALKS THE LINE: It may shock y’all to learn that the actress Reese Witherspoon—who honky-tonked her way to an Oscar in Walk the Line, and “bless her heart”-ed all over Sweet Home Alabama—is a Southern belle in real life. D.C. gets a little more precious on Saturday when Witherspoon comes to town on tour to discuss her book of recipes, party-planning, and memories, Whiskey in a Teacup: What Growing Up in the South Taught Me About Life, Love, and Baking Biscuits. At the Anthem, she’ll be in conversation with her Big Little Lies co-star Zoë Kravitz. (The Anthem, 8 p.m., $120-$145)

MORE: Technology Family Day (Smithsonian American Art Museum, 11:30 a.m.-3 p.m., FREE), Craft Your Own Hot Sauce class (H Street Farms, noon, $30), #GrownAF: Back to Cool Party (Wicked Bloom, 9 p.m.-3 a.m., $10-$15)

SUNDAY, SEPTEMBER 23

THE WORLD OF FASHION: We can’t guarantee you’ll spot Mary-Kate Olsen at DC Fashion Week, but if the wife of Frenchman Olivier Sarkozy were to attend our humble festival of haute couture, she’d likely make an appearance at the International Couture Collections Showcase, which includes the work of designers from around the world. Her uniform of giant sunglasses and constant chain-smoking would fit in at the French Embassy, d’accord. (Embassy of France, 5 p.m.-8 p.m., $70)

SHE MAKES: Just as the National Museum of Women in the Arts celebrates the work of female artists, its MakeHER Mart will offer crafts and retail items from local female designers and makers. Items include jewelry from Kicheko Goods, stationary from Typecase Industries, and extremely adorable baby apparel from Lil’ Fishy. (National Museum of Women in the Arts, 10 a.m.-4 p.m., $10 at the door)

EAT TILL YOU DROP: If fighting through the throngs of strollers (both slow walkers and baby conveyances) that populate the streets of Georgetown, head to Washingtonian’s Taste of Georgetown, where you can fight through crowds and over bites of food, too. You’ll pay for each snack or glass of beer or wine from vendors—including The Dough Jar, Bluestone Lane, and Via Umbria—with tickets, priced from $11 for 2 up to $44 for 10. That stretch of K Street is covered, so you can still snack even if it rains. (K Street NW between Wisconsin Avenue and Thomas Jefferson Street, tickets available onsite)

MORE: Yoga at the National Building Museum + Museum Tour (National Building Museum, 10 a.m.-11 a.m., $20), DC State Fair (Waterfront Metro Station, 375 and 425 M St. SW, 11 a.m.-8 p.m., FREE), Pints for Pets (DC Brau Brewing Company, noon-4 p.m., free entry)
