Depends entirely on the brand of cute. Some people think nerdy guys are cute. Some people think feminine boys are cute. Some people think guys with broccoli hair are cute.
It really depends.
As for what I like, oversized hoodies with cozy graphics on them, eyeliner, retro shorts (“booty shorts”), longer socks or thigh socks, super fluffy hair (look up “wolf cut”) or long hair, piercings, nail polish, lots of color. Those always are cute on a guy in my opinion.
