Could you tell me what the girl is saying in this video?: https://www.youtube.com/watch?v=73nRwnfTPkc

These are some phrases I tried transcribing, and "(??)" refers to the point where I got lost.

At 4:27: But sometimes you just need clothes to wear unfortunately so when (??) I'm gonna go check it out and see what they have.

At 4:51: I'm kind of surprised that they don't just air condition the entirety of Ginza, like they could put a (??) dome on top of it and just aircondition it.

At 5:50: Yeah I'm not feeling it, but I'm feeling a Troye Sivan.
(Here I don't understand the meaning of the entire sentence.
Is she saying that she don't feel like buying clothes, but is happy to listen to Troye Sivan?)
