Pippa Middleton stepped out for Prince Louis's christening, there to support her sister, Kate, who chose white Alexander McQueen for the occasion. Pippa could've selected her design, a custom Alessandra Rich shirt dress with long sleeves, a pleated skirt, and a drop waist, button-adorned bodice, simply because she liked it. Or, yes, she could be making a statement with that baby blue shade. Whether it means Pippa is expecting a boy with husband James Matthews or she's just making like Kate, who wore blue over and over throughout her third pregnancy, we like her in this look quite a lot. Read on to see how Pippa finished her outfit with a netted fascinator, silver, ankle-strap heels, and a satin clutch, then shop some inspired outfits for your closet.
