Summer's still a month away, but celebrities are already putting on their denim sleeves. Over the weekend, Katie Holmes wore a navy blue scoop-neck T-shirt with ultra-wide blue jeans. And yesterday, Reese Witherspoon also wore the fall 2024 denim trend.

The actress was photographed showing off a pair of light-wash wide-leg jeans on location for "The Morning Show" on Tuesday, July 30. Witherspoon dressed up her denim with a dark navy blazer, black suede bootie heels, a black Saint Laurent medium quilted leather shoulder bag, and a simple gold chain necklace. It is unclear if this outfit is original to Witherspoon or to morning show character Bradley Jackson. Sophisticated, normcore business casual could be either.

Last week, Marie Claire predicted the biggest denim trends for fall 2024. Among them were dark washes, baggy fits, skin-tight silhouettes, mixed materials, and ultra-wide legs. The stars are beating the heat and trying out their own trends ahead of time. Meghan Markle wore a Lady Dior bag last week with classic high-waisted blue jeans with cuffs and a crisp white button-down. Meanwhile, Jennifer Lopez paired her favorite denim trend, baggy sweatpants-like denim, with a tweed blazer and a Birkin bag. Last month, Blake Lively suggested a new denim trend with her $19,000 cutout Valentino jeans. (This is the next step in the controversial "jorts" revival, a return to basics. Let's be thankful.
