If you knew your friend was wearing a dress to an event, would you buy the same one and wear it too? Would you go to someone’s home and then decorate your living room identically, down to the curtains? How about liking a website and then imitating it, what would that say about you? I’ll tell you, it says you are a shameless copycat and copycats aren’t chic.
Being inspired by someone’s creative style is great, but blatantly copying them, especially their hard work, is not. Copying shows a lack of original thought and more importantly, hurts the person you steal from. If you see something that you like, give credit to the creator, that is the gracious thing to do.
