The pregnant royal, who is expecting her third child with Prince William later this spring, weathered the storm in the chicest blue maternity ensemble. Middleton wore a Seraphine cashmere blend maternity coat that's under $300— $299, to be exact—and it's still in stock! She paired the baby blue maternity coat with a $109 floral printed dress. Are these blues possibly a hint about baby No. 3? It's unclear, unfortunately—especially since Middleton has been known to wear plenty of pink during this pregnancy.

She went out to shed light on an issue that impacts mothers around the world—postpartum illnesses. She stopped by King's College London to the Maurice Wohl Clinical Neuroscience Institute to visit the laboratory and learn of its perinatal research.

Sounds like a rainy day well spent.
