Khloé Kardashian doesn’t hold back – even if that means throwing a little good-hearted shade at one of her sisters.

In a sneak peek at Sunday’s Keeping Up with the Kardashians midseason finale, Khloé is hanging out at home with her brother Rob when sister Kim walks in wearing one particularly … revealing outfit.

“Oh my – you’ve got to get out of here,” says Khloé, 32, laughing as she eyes Kim’s skintight black minidress and choker.

“What?” Kim says as Rob starts laughing.

“Kimberly – how much are you?!” Khloé demands.

Kim, 35, acknowledges the outfit might be a little much.

“I know, the neighbor did kind of look at me like: ‘Hooker city,’ ” she admits, laughing. “I did feel uncomfortable for one second.”

“You literally look like Rob paid for you,” says Khloé. “I literally just dropped my jaw when I saw you. Wow.”

“It wasn’t a bad ‘wow,’ ” adds Rob, 29.

The conversation then takes a more serious turn as Khloé addresses the tension that’s been brewing between Rob and his fiancée Blac Chyna.

“What’s going on?” asks Khloé. “How’s everything on the home front?”

“I mean, it’s been tough,” admits Rob. “It takes one person to man up – obviously that’s going to have to be me. But at the same time, I’m not going to argue with a female. We had a good talk the other night, so we’ll see.”

Rob explains the two had an argument that he “took to heart.”

“Because you’re sensitive,” says Khloé. “You have to worry about Rob and how you can be strong and better for you and now your baby. Don’t you want to get your s— together?”

“I do. My plan is not to have a kid with somebody and not be with the person – that’s just bizarre to me,” he says.

“I know Rob and Chyna have a long way to go, but I’m really happy that they are working things out,” Khloé says in an on-camera confessional. “Relationships are hard no matter what, and as long as Rob is trying and starts engaging and communicating, that’s all I could ask for.”

Keeping Up with the Kardashians has its midseason finale this Sunday at 9 p.m. ET, and Rob & Chyna premieres Sept. 11 at 9 p.m. ET, both on E!
