Yeah, it's the same outfit —
It's also the same outfit as the scene when someone presents him with Daniel's book and seemingly asks for his autograph —
It's also the same outfit as the scene of him and Dee walking into his apartment and the presumably continuing scene showing Lestat with his guitar and Dee sleeping in the foreground —
Lestat....is not happy. He's in a very dark, depressed place. His relationship with Louis is fraught, and Hannah confirmed during NYCC that Louis has actually regressed from his ending in S2. Louis is not at peace either and while Lestat is doing this for Louis, the book painted Lestat as a monster and also revealed the true horrors Louis had endured since leaving New Orleans, including the bombshell of Armand putting Louis' life at risk by taking him outside during daylight hours.
We've already seen the glimpse of Lestat intentionally fucking with Daniel and playing up the façade of the expected monster he was painted to be —
We also know from Lestat's argument with Louis in the mediation scene that he's piecing together the fact Louis' mind has been fucked over by Armand. I talked about that here, here, and here.
Lestat is also upset over what Armand did to Claudia and the fact Louis went off with him in the aftermath and instead of taking this seriously, Louis is being condescending and defensive and demeaning to Lestat. Louis is deliberately trying to poke at the wound.
So with all that ^^ taken into account, Lestat and Daniel? They're not going to be buddies for a good long while. I think they might come to a place of understanding later via Lestat's trauma with Claudia and Daniel's trauma with his own daughters, but Lestat won't trust Daniel due to what happened with Louis and the book, and Lestat will have the walls up.
I think his relationship progressing with Louis and the dangers becoming more blatantly heightened threats throughout the season will work in tandem with how Lestat's relationship progresses with Daniel.
Oh and Eric also spilled that Daniel tries to flirt with Gabrielle before realizing she's Lestat's mother, and that will inevitably add another shade of disdain from Lestat's POV to color their relationship.
We better fasten our seatbelts, because it's going to be a messy ride. The dynamic between Lestat and Daniel and Louis and Armand is one of the big elements I'm most excited to see. They all tie together. 😬
