Multiple outlets report that Kate Middleton and TV presenter Cat Deeley have both been spotted wearing oversized blue shirts. The articles frame the sightings as part of a broader spring wardrobe refresh, highlighting the popularity of “hero” shirts and oversized fits for warmer weather. One report identifies the blue shirt style worn by the two public figures and points readers to retailer options, including Boden, M&S and WNU. The coverage emphasizes that these shirts are presented as spring clothing staples rather than commentary on any specific event or storyline. Across the sources provided, the key shared element is the appearance of both women in similar oversized blue shirts, along with follow-up information aimed at helping readers find comparable items from mainstream retailers. The articles do not indicate any coordinated campaign; instead, they treat the outfit sightings as separate instances of a fashion trend in the spring season.
