December is here, and that means a month of fabulous festive fashion. November teed us up nicely for a strong sartorial month, what with the Fashion Trust Arabia 2025 Award Ceremony in Doha and the LACMA Art+Film Gala drawing an array of A-listers onto the red carpet, from Cynthia Erivo and Elle Fanning to Demi Moore making waves in their finery.
This month has certainly started off strong with The Gotham Awards, celebrating a year of great film, in the presence of Julia Roberts, Kate Hudson, and Jennifer Lawrence . Across the pond, London played host to The Fashion Awards. As HELLO!'s Lifestyle writer, I love seeing what the stars wear to this cornerstone fashion event, and if you ask me, Cate Blanchett's look topped the lot.
Celebrity stylist Ellis Ranson was also a fan. "I love anything that blurs the line between a tuxedo and a gown with the classic tailoring details, the satin lapels, the white cuffs, all feeling perfect for the first night of December," she tells us.
"The minimal hair and accessories let the gown do the talking, and rocking a blazer dress is something we can all achieve for our Christmas parties. The whole look feels powerful and elegant with a touch of sexiness."
