Yuuri turns into the kiss on his cheek immediately and the kiss is surprisingly heated. It's a lot like that last kiss in Japan, open and grateful, while Yuuri grounds himself a little. That it's a reward for fixing the issue so quickly is immaterial.

"Th-thanks," he flushes, pulling back and taking the clothes, maybe shuttering off a little bit, but if he doesn't they're just going to make out in the dressing room. A moment later, he moves to the partitioned area to change. He's obviously not concerned about being naked around Viktor-- he's seen the man naked even before they were sleeping together and vice versa-- but he does kind of want there to be a reveal of sorts.

He can't get the scarf back around his neck with the same flair, but he's stepping out a moment later in the pants and the sweater and his eyes are doing the thing again,

"It's... so soft..." look, he's never had nice clothes before and when he steals Viktor's it tends to be t-shirts and button ups. He has no defense against being wrapped up in something like this.

Also he's probably adorable in what's likely close to a thousand dollars worth of clothing and his sock feet, looking nervous.
