We'll preface this with the acknowledgement that Kate dresses Charlotte, so it's not surprising they're both often seen using this styling trick, but it's rare for a trend to suit both a child and an adult who spends most of her life greeting royalty.
Princess Charlotte, as is traditional for young royals, is often seen wearing a blouse or dress with a Peter Pan collar peeking out over her coat, sweater or cardigan.
Now we've noticed Kate stepping out with a Peter Pan collar over the neckline of her collarless coat—which is important mainly because most of us struggle with what to wear with a collarless neckline. A crew neck is too high, a regular collared shirt looks messy and a chunky knit just makes it look like our neck is too small for our body. So thank you, Kate and Charlotte, for this obvious and regal solution. Shop a few of our favorites here.
