so obviously, atem shares a body for most of the series, so his appearance is essentially Yugi's. however, there are still a good amount of differences specifically to show their differences.
Yami's hair gets a bit crazier, his eyes a bit closer to red than Yugi's amethyst irises, and we can't forget about the infamous "bondage slave" look. Originally, in Season Zero, when he would take over he would also don large Ankh bracelets around his wrists, and we see this trend continue later in the series, with more bracelets. There is also the signature look of the jacket cape, as if to switch up Yugi's regular school uniform look.
these differences, although not huge, are still enough to show a difference between Yami and Yugi, even when he has no identity of his own. Yami's outfits are flashier, giant Ankhs and big wrist cuffs, big black strappy boots and a jacket cape to make even a Domino High uniform look like so much more. he wears Yugi's same clothing, but in a new way, and perhaps this is influenced by his confidence, the pride in his walk and the way he keeps his head held high, but even in a high school uniform he can still look regal, commanding attention of those around him.
when he's not sharing a body with Yugi, the look still continues. in modern times, he'd likely be partial to dark clothing, with a few accessories. dark t-shirts and flashy jewelry with some tight fitting pants. the flashy jewelry a left over from the gold he was so often adorned with in ancient Egypt. he commands attention with whatever he wears, he would dare to be different. he wears what he likes, with no fear of what others will say. he may not be the loudest person to walk into a room, but he certainly does not care what others think of him.
"how do they relate to their appearance? how do they wear their clothing/style/etc?"
