If you’re headed to a destination wedding in the South of France, Lake Como, or any other summery spots to celebrate someone’s nuptials, wear something that embodies the “Euro Summer” vibe.

Between the eye-catching shades of blue and sculptural gold hardware adorning the halter neckline, it’s made for a European destination this summer.

We understand the need for more budget-friendly options for the frequent wedding-goer. Thankfully, several styles exist under $200—our favorite is this baby pink ASOS dress with dramatic ruffled shoulders and a chic ruched bodice.

What to Look for in a Summer Wedding Guest Dress

• Fabric: If you’re attending a summer wedding, it’s wise to shop for summer wedding guest dresses made from breathable and comfortable fabrics like linen and cotton. These lightweight fabrics will keep you cool—especially if the wedding is outdoors—and work for every type of dress code. 
• Silhouette: When it comes to silhouettes, mini, midi, and tea-length dresses are ideal for summer wedding guest dresses and work especially well for beach and garden venues. However, any full-length dress is suitable, as well, especially if they come in the aforementioned breathable fabrics. 
• Style: Attending a summer wedding is also the perfect chance to experiment with fun prints and vibrant colors. When selecting a dress with bold hues, consider the bridal party’s color palette. Wedding guest dressing etiquette suggests that you want to avoid clashing or drawing too much attention to yourself as a guest.
