Kate Middleton had some time out with her family, including husband Prince William, and kids Prince George and Princess Charlotte over the weekend to watch Houghton horse trials in Norfolk. She was dressed casually in her favorite navy and white-striped Breton T-shirt and gray skinny jeans. Her long brunette locks were left loose and swept away from her face with an Alice band.

Since July 2012, Kate has been spotted wearing Breton T-shirts on at least eight separate occasions. For a busy mom with two kids, it has become Kate’s favorite off-duty style. The Duchess of Cambridge wore her 85 pounds ($122.71) “Tori” version of the T-shirt from Ralph Lauren during the equestrian event.

The navy and white Breton sweatshirt featured a flattering cut and bold stripes. It also had long sleeves. Kate was pictured playing with George and Charlotte in the grass in her favourite pair of skinnies and Breton T-shirt. The royal mom appears to own three versions of the Breton sweatshirt that’s she sports regularly.

Kate opted for a tortoise-shell band to hold back her glossy, brunette tresses. The Alice band was a childish, nursery-inspired trend beloved of Sloane Rangers in the 1980s. In fact it was Kate’s stylish mum-in-law Princess Diana, who helped set the Alice band trend in the 80s. Named after Lewis Caroll’s Alice, who in illustrations wore a ribbon round her head, the bands could be velvet and padded, thin and plastic, and fat and embellished.

Italian designers Dolce & Gabbana have tried to make jewelled versions of the “anti-fashion” Alice bands with net bows. However, Kate’s printed plastic hairband was not the fashionable version from D&G. Celebs like Cressida Bonas, Gwyneth Paltrow, Rita Ora, Emma Watson have been spotted wearing various versions of the hairband.
