Sporting those massive sunglasses was super cool. And those skinny jeans? Totally tight.

But savoring an icy treat? That’s sweet. Tangysweet, to be exact.

The new shop is sweetening Dupont Circle with three flavors of frozen yogurt: classic (the tart must-have for the Pinkberry set), green tea, and pomegranate. Toppings include fruit (locally sourced when available) and “scrumptious crunches” like cereals and nuts. They also do custom smoothies.

Tangysweet plans to stay open until 2 a.m. on weekends. Make it a destination: The space features rainbow LED lighting and outdoor seating. And best of all, they’re open just in time for the sticky, humid days of summer.

That’s hot.

Tangysweet, 2029 P Street NW, between 20th and 21st Streets (202-822-2066 or tangysweet.com).
