I saw a post about robots in clothes and my brain has unlocked its hidden potential. This isn't the last of the cybertronian fabric ideas I have so watch out for that 😌✨️
Flash would absolutley fuck with clothing. Maybe he went to Iacon one time, and with it being a larger city and more populated area in general, they'd have more imports from other planets and mimics of said imports. Long story short, he tried on some organic fabrics and he was in love. The feeling was cozy, he could get pieces that accommodated his door and wheel-wing situation, and it just felt like he had a thermal blanket on him all the time.
I think also that on Earth humans would realize that there was a market for Cybertronian-size clothing or bedding and thought it was cool, so you would see people of all ages going to fabric stores and buying meters upon meters of fabric at a time for these huge projects.
Also, gag gifts would definently be a thing, or just more raunchy clothing would be on the market too (because, come on. There's gotta be at least one freak who'd make alien robot sized lingerie, and there'd also be one or multiple alien robot freaks who'd buy it.) but these shorts were a gag gift made specifically by one of the frequent human friends on the base Anders, and his buddy Intel, who made the shorts pictured. (which were inspired by this post)
Side note! In this universe it's similar to Earthsparks continuity where humans are aware of the cybertronians existence, and the war is over, but Megatron isn't 100% forgiven. He's still got some work to do but he is able to live at the base because he did side with the Autobots at the end, BUT Optimus hasn't 100% forgiven him yet since it's only been a couple human years since the war properly ended. A lot has happened in the process of it and they've lost lives on both sides, and even though it's ended now, it's still very fresh in Cybertronian standards.
ANYWAYS! Lore aside, I love the idea of robots loving clothes because it's cozy for them. (Also maybe the more... silly bits to it too but mainly the cozy bit.)
