We've put Sienna Miller's 'feline' lash trick to the test - along with her go-to mascara

As a team of mascara lovers, when a new formula hits the shelves we're often first in line to try it out - especially when a certain A-lister shows us how it lifts and elongates her lashes in real-time. That said, it was the way Sienna Miller applied this particular formula that had us racing to get our hands on it...

When it comes to the best mascaras, we all have our personal preferences. Half our beauty team, for instance, favour a subtle lift while the rest invest in the best volumising mascaras for boosted definition and curl. We all found some common ground, however, when we clustered together to watch Sienna Miller's tutorial on Charlotte Tilbury's latest lash formula, Exaggereyes. The star demonstrated exactly how she achieves 'feline'-like flutter and let's just say, we were simultaneously impressed and perplexed.
