The fact is, to achieve a cat eye exactly like Grande's — or any other specific person's — you need to have the same eye shape as them. "It's going to be different on everybody because everyone has different eye shapes," said Chinchilla. "The way I do it on one person is going to be different than how I do it on another."
The universal key: having the right tool.
"With a lot of eyeliners, it makes doing a cat eye a little tough, the tip is too thick," said Chinchilla. "People go overboard and then they just give up, when, really, they just had the wrong product or the wrong tool." That's why Chinchilla loves the KVD Vegan Beauty Tattoo Liner (£16) so much. "The brush is so fine that it makes it really easy to create a wing."
