What to Wear to an August Wedding 2023
In general, you'll want to follow the wedding dress code, plan for the style of the wedding, venue, time of the ceremony or reception, and the typical weather at the location of the wedding.
Here are some of our picks based on the warm late summer weather we usually see in our area. These featured dresses are great for many of the dress codes and invitation scenarios you'll see for August weddings. Read more below for our thoughts on when and where to wear them.
Daytime or Dressy Casual Wedding in August
This bright floral print, bright yellow color, and easy silhouette just suits a hot summer day. If you're attending a daytime wedding that starts in the early morning or afternoon a midi dress like this with spaghetti straps is a great choice!

Afternoon Wedding In August
If you have an afternoon August wedding, either in an outdoor venue or a combination of indoor ceremony and outdoor we love a high-low style that splits the difference between casual and formal. The bright punchy color of this rental dress is eye-catching and festive, but very wedding guest appropriate. This dress is a rental.

Formal August Wedding
Blending the warm weather dressing with a long gown that is usually required for a black tie optional, black tie, or formal wedding can be tricky, but not impossible. Our recommendation is to pick a maxi dress or formal gown floaty fabric that doesn't cling, in with a summer color or floral print like this gown. Elevate the look with formal heels, jewelry and a clutch for a black tie look!

A Late Summer Outdoor Wedding
In warm summer months like August, outdoor weddings and outdoor receptions abound. Since the late summer weather can pack some serious sun, heat, and humidity, an easy midi dress with cutouts could be one great way to go!

The end of summer makes it a prime time to have those beachfront weddings or weddings in a seaside resort or other coastal setting. If you've been invited to a beachy wedding in August here's one idea for what to wear.
If you need more ideas, we have so many other picks for guest dresses for beach weddings.
Maxi Dress for Late Summer
We think the maxi dress is one of the most versatile styles of dress for wedding guests. A short sleeve wrap maxi dress or sundress style maxi dress so often works for a daytime or afternoon wedding. While that same dress with more formal accessories and makeup and hair styling can work for a black tie wedding.

Classic Cocktail Style
The cocktail dress or a midi dress is our usual go-to for a classic semi-formal wedding guest style. We gravitate towards the brighter colors for August. This look combines bright colors for the need of summer along with a fitted off-the-shoulder cocktail style.
