Cocktail and Casual Summer Wedding Guest Dresses

Summer brings sunny skies and warmer temps, so it's no surprise that many couples choose to host their event outside this time of year. Since outdoor venues are not usually as formal as say, a banquet hall, dress codes tend to lean a bit more casual. That said, you'll have a chance to embrace a more laidback vibe when picking out your outdoor wedding guest dresses.

Dresses for outdoor summer weddings don't need to be floor length if the invitation indicates a cocktail attire or causal attire dress code. Instead, opt for a summer outdoor wedding guest dress in a mini or midi-length silhouette. When it comes to colors and patterns, the bolder the better (think: neons, florals and tropical prints). You can accessorize cocktail and casual outdoor wedding dresses for guests with a pair of sandals or wedges and a stylish clutch.

Below, we've rounded up 20 of our favorite casual summer dresses for weddings and summer cocktail wedding guest dresses. You might be wondering what makes them our favorite. Well, in addition to being stylish and seasonally-appropriate, they can also be dressed up or down to your liking, meaning you'll be able to re-wear them all season long.
