The only answer we could come up with? The stylish blouse she wore for the occasion. We've seen plenty of Middleton this past week thanks to the Platinum Jubilee, which celebrated the Queen's 70 years on the throne. Accordingly, her fashion has leaned more formal: Among other outfits, she wore this sunny-yellow belted dress that's an instant mood booster and this crisp white blazer dress that was elegance to a T. But we're perhaps fondest of this down-to-earth style sighting from the gathering. Duke and Duchess of Cambridge/Instagram Middleton's baking uniform consisted of a trusty pair of light-wash jeans and the cutest red gingham-printed blouse that she tucked into her denim. There's so much to love about this summer-perfect top — the print! Those sleeves! — but the real standout detail is that Peter Pan collar.

The collar adds just the right amount of preppiness and femininity to a look without feeling overdone. But this frilly neckline is actually nothing new: Middleton herself has gravitated to it over the years. And in fact, Middleton's late mother-in-law, Princess Diana, was quite the fan of oversized collars, regularly making them the focus of her outfits.
