We all have one thing that we wear all the time.

Whether it's a watch, your favourite hat or your trusty bag, it's your staple, and as small as it may be, it's what defines you from others.

Well, Kate Middleton has one staple that she wears to every occasion – her pearl drop earrings.

Hello Giggles spotted that the Duchess just can't be seen without them:
