Our editors independently research, review, and recommend the best products. We may receive commissions on purchases made from our chosen links.

Suns out, styles out - it's time to shop the best summer wedding guest dresses as peak wedding season approaches.

 

While we’d never turn down the opportunity to shop for gorgeous occasionwear, if we had to choose, summer would win every time! And that's not to say there aren't heaps of stunning autumn wedding guest dresses, winter wedding guest dresses and spring wedding guest dresses. There's just something special about summer. 

If you have a special ceremony to attend between peak wedding season this year, the Rock My Wedding editors have scoured all the latest collections to bring you only the best summer wedding guest dresses

From beach weddings to garden parties - there's so much to consider when choosing the perfect frock. While lightweight materials and delicate florals are a win year after year, finding your dream dress that takes you from day to night is no easy feat. 

For those keen to keep up with trends, while you can expect the classic bold and bright colours to appear in summer 2025, expect a softer, more buttery, less saturated and more romantic variations to take the lead this year, including the all-time favourite, butter yellow!

So, while yes, we have a bit of a soft spot for May through to September, that doesn't mean we won't help you find some of the best wedding guest dresses all year round! 

But, for now, let the summer shopping commence!

For SS25, we're all about standout shades, but make them soft and romantic - what could sound more appropriate for a wedding guest look to remember! Finding the perfect wedding guest dress is about striking a balance between something that makes you feel incredible yet doesn't outshine the bride, and we're here to help you get it right every time. 

Finding a wedding-appropriate gown definitely doesn't equate to shying away from colour! While we're also fans of muted tones and warming nudes - even in the summer months - colour always wins for us when the sun is shining. Bold colours at weddings? Absolutely! When paired with elegant midi and maxi lengths, delicate prints, and tasteful design features like ruffles and modern, asymmetrical necklines, colour is a surefire way to make a statement within the constraints of all dress codes and themes.

For gorgeous styles that will see you through all your summer weddings this season, we can't get enough of retailers like Nobody's Child, Anthropologie, Pretty Lavish, Mango and more!
