Two pieces are all the rage this spring, and we love this formal set in a bright yellow hue. The strappy cowl neck top creates a visual appearance that elevates the typical slip dress silhouette that's become a guest favorite. Don't forget to buy the matching skirt too!

This ethereal dress is the embodiment of springtime thanks to its light green pattern and tiered ruffle skirt. Plus, with a flattering tie waist and comfortable mid-length sleeves, you'll want to re-wear this pick throughout wedding season.

In a sea of pastels and floral prints, you'll stand out in this jewel-tone stunner. While satin is an effortlessly elegant fabric choice, this dress is perfect for formal spring weddings thanks to the trendy cuffed sleeves and structured shoulders.

Can't get enough of the cottagecore trend? We feel you, which is why this puff-sleeve maxi is on our list of favorite spring wedding guest dresses this year. With a bustier-style bodice and ruffled bottom hemline, everyone will be asking you where you got this look.

Florals for spring aren't necessarily groundbreaking, but there's no better time of year to rock a lovely flowered frock. Enter, this floral dress from Reformation. We love the angular square neckline, which is juxtaposed with a soft, oversized flower print.

The long sleeves are especially fitting for a March wedding that falls right in the middle of the season.

You might associate jewel-tone dresses with fall weddings, but we're here to make the case for spring too. This sleek emerald midi has a twisted ruched bust with cuffed balloon sleeves, but we particularly love the open back too.

Spring cocktail dresses for weddings don't have to be stiff and uncomfortable. The unique fabric of this stretchy ruffled midi will accentuate your curves in all the right places. Plus, tiered ruffles and a smocked bodice make this an exceptionally trendy option.

Who says something blue is just for the bride? This size-inclusive chiffon maxi is a lovely choice for spring wedding attire—just add your favorite metallic heels and jewelry to make your outfit luminous from all angles.
