29 best long sleeve wedding guest dresses that are seriously chic
Long sleeve wedding guest dresses are a chic and sophisticated option for weddings this year, so say SS25 trends anyway.
2025 is set to be another major year for nuptials with A-listers like Zendaya and Tom Holland, and Dua Lipa and Callum Turner reportedly engaged, but often times its what we see on the catwalks that influence our wedding guest attire.
This season, it’s all about opulence, romance and a touch of the unexpected. Designers like Saint Laurent, Schiaparelli and Valentino are embracing a “more is more” aesthetic, adorning sweeping gowns with intricate brocade, jewel embellishments, dreamy draping and, you probably guessed it; long sleeves.
Minimalism is taking a graceful step back, making room for a new era of soft power-dressing, where fluid tailoring meets understated luxury. Think effortless sophistication that feels just as powerful as it does feminine.

For those drawn to a little drama when it comes to the best wedding guest dresses (and let’s be honest, who isn’t?), SS25 has something for you too. The sheer trend is captivating with frothy tulle, lace and fairytale-like hues that bring a romantic edge to occasion wear.
On the flip side, the 3D floral trend is delivering playful volume with garden appliqués, bubble hems and exaggerated silhouettes proving that elegance doesn’t always have to take itself too seriously. So if you’re leaning into decadent embellishments, soft romanticism or avant-garde shapes, this season is all about making an entrance.
