Something I find interesting is that in every form Aaravos takes in episode 2 of season 7 we see all his elf forms showing some of his skin other than his face. For Skywing he’s literally wearing a crop top (or something of the sort) with his arms bare, Sunfire has his hands shown, Earthblood has his entire chest is unclothed, Tidebound has his waist and arms shown, and Moonshadow has his midsection and arms unclothed from what I remember.
The only form he takes where he’s not showing any skin other than his face of course, is his human one. He’s literally wearing gloves with belts practically trapping him in. I thought maybe it was to show the difference between his human disguise and his Startouch form since Startouch elves tend to have their main star showing from their clothes and tend to dress in more flowing fabrics. But it could just be overthinking from watching this episode too many times.
