From the runway to real weddings - why butter yellow is 2025’s must-wear guest dress colour.
Let’s talk about the butter yellow trend - because if you’ve spent more than five minutes on TikTok, Pinterest or Instagram lately, you’ll know this soft, sunny hue is everywhere. Bridal parties, wedding guest outfits, even street style - it’s safe to say that butter yellow is staging a full takeover for spring/summer 2025. And honestly? We’re here for it.
While not an entirely new arrival (we first spotted hints of this mellow yellow in our round-up of yellow bridesmaid dresses last year), butter yellow has been elevated from emerging favourite to full-blown fashion fixture. It’s less "sunflower" and more softened sorbet - a shade that flatters everyone and feels fresh without trying too hard.
Designers from Toteme to Chloé have embraced it, with creamy yellow pieces floating down the runway in everything from maxi dresses to oversized tailoring. At weddings, it’s fast becoming the alternative to blush or sage green for those in the know.
So, if it hasn’t already snuck into your spring wardrobe, butter yellow is coming - and we say: let it. Below, we’ve curated the best butter yellow wedding guest dresses for 2025, whether you’re heading to a garden party or destination wedding. You’re about to find your main character moment in the softest shade of the season.
