okay so this is impossible to generalize haha so let me tell you my favorite styling by member:

Chan: the colorful sport style one with the tiny braids
Minho: sleeveless black shirt
Changbin: silver outfit
Hyunjin: tight green (?) shirt one
Jisung: the ripped black jeans
Felix: full denim
Seungmin: the silver one (difficult pick because there aren't many shots that fullly show his outfits)
Jeongin: sleeveless grey shirt
