Mary-Kate OlsenMary-Kate OlsenSometimes, celebs just can't be bothered.

We could see this decision in a positive light - these stars are so sure of themselves, they don't need to dress to impress.

On the other hand, we might equally view them as lazy 'uns, who should really pull their finger out and just dress up proper.
