19 Times Pippa and Kate Middleton Dressed So Similarly, We Had to Do a Double Take

If Mary-Kate and Ashley Olsen have mastered comfy-cool, and Malia and Sasha Obama can pull off any trend, then it's time to crown Kate and Pippa Middleton as the world's most polished — and impeccably chic — set of sisters.

And now that Pippa is expecting her first child, we can't wait to see if she emulates Kate's maternity fashion.

Read on for a few times Kate and Pippa were stylishly in sync — so much so, we swore they were fashion twins. Then check out Pippa's favorite dress style.
