Winds of Chaos

Is it possible for an Elf to use non-magical means to Disguise themselves as a Human?

Obviously ears are an issue but let say they cover them with hair, hat, hood or clever prosthetic or are their proportions and features literally too Elven to pass?

There are humans with those aquiline features. But those eyes would be a big giveaway. If the target of the deception has no familiarity with elven features one could make up that they're from a distant country to explain the eyes, might work.

Yes I'd imagine you could fool peasants and lower intelligence humans and halflings, but well-educated or well-traveled humans and any dwarfs or elves would be able to spot the disguise right away.
