I mean... maybe not "better" outfits, but for Nayeon in the early days certainly some outfits that had a notably stand-out colour (e.g. Knock Knock). Same for Jennie - everyone has a black top but here's Jennie with the white/silver head to toe (4D).
Why pretend certain members don't get styled to stand out when they clearly do? I'm not even commenting on whether it's right or not, it's just...true.
