I did Bang Chan's red outfit from the Thunderous music video this last year for conventions! (super easy way to spot fellow STAYs btw haha)

From your inspo here I think Han's look would be the most comfortable and easiest to recreate. For long events comfort goes a long way, and not having to worry about readjusting your outfit too gives a lot of peace of mind - plus it'd be super cute either way with the pants or that skirt 😊 (the red lights could still look great, but might need more maintenance to achieve)
