Rich, deep shades tend to dominate our autumn capsule wardrobes, with hues of burgundy, mocha and warm neutrals the perfect cosy tones for the season. But if the autumn/winter fashion colour trends for 2025 have taught us anything, it’s that incorporating brighter colours into our seasonal looks is a surefire way of inducing some dopamine dressing.
Still, they can feel daunting to style. That’s why we knew we’d found the ideal outfit formula for bold autumn outfit ideas in Siân Brooke’s bright green suit trousers ensemble, which makes wearing striking colours a breeze.
The Blue Lights actress stunned in an appearance on This Morning last week, with her green suit trousers catching the eye amidst the October gloom. But by pairing the bold colour with a bright white neutral shirt and matching her shoes to her blouse, she sandwiched the statement hue in the middle, which helped to tone down her whole look, making it feel instantly more wearable.
