They look like normal people

but with more black

Wearing black a lot is more goth Emo is more like your emotions and music taste, not appearance

Goth is more wearing horror inspired clothing, like dressing like vampires and stuff, and wearing saturated dark colours, like deep dark reds purples and blacks. Emo is like being mopey and wearing neutral grey and black colours and hoodies, edgy t-shirts, jeans and stuff.
