Top picks:

For ultimate versatility

Midi dresses work for a variety of wedding themes and special occasions. These versatile styles can be dressed up or down with the right accessories, and are safe picks for most wedding dress codes. Slightly easier to pack than a long gown, this style remains just as elegant and timeless as a maxi. Cocktail dresses, like the patterned Utnisan dress or the chiffon Zesica midi, are great for just about any special affair you’re attending, whether it’s a party-filled destination wedding in Bogotá or an alpine-inspired ceremony in Switzerland. Prettygarden’s elegant mock neck dress is another trendy contender. A notable plus of these Amazon wedding guest dresses: Most are available in a variety of colors that work in multiple seasons.

For casual ceremonies

If the couple-of-the-hour is a bit more lax—and say, opting in for a no-frills type of beachside wedding—there’s a chance the dress code is marked as casual. This means flowy maxi dresses, breezy sundresses, and floral prints are all fair game. If you’re walking on sand or grass, these casual dresses can be worn with a comfortable pair of sandals instead of a heel. Rewear these dresses to lunch dates, picnics in the park, and bridal or baby showers all summer long.

For black-tie affairs

While a black-tie affair calls for an unmistakable sense of spiffy, that doesn’t mean you need to splurge on an exorbitantly priced gown. Affordable luxury can feel just as stunning with these under-£100 dresses that epitomize sophistication and style. Ymcuch’s sleek, black off-the-shoulder dress, in particular, exudes timeless charm—its simplicity allows you to shine without overdoing it. Vubiya’s strapless dress is elegant and made with breathable, light satin. These dresses need little else to make a tasteful statement and promise to turn heads—all without stretching your budget.

Ever-Pretty

Long evening dress

For warm-weather destinations

At sun-soaked weddings, warm weather demand attire that’s as breezy and radiant as the setting. Here, lightweight mini dresses are your best bet—offering breathability and movement. These dresses are perfect for navigating sandy beaches, garden ceremonies, or tropical terraces, all while keeping you cool and comfortable. With the right touches—perhaps a delicate chiffon fabric or a playful floral print—your dress becomes more than just wedding attire; it often has potential to become a future wardrobe hero, too. From a romantic destination ceremony to a local sunset cocktail hour, these dresses are as versatile as they are chic, pairing beautifully with strappy sandals for a laid-back vibe or elegant heels for a more elevated look.

For maximum comfort

For those who want to dance without restraint, mingle with ease, and still exude sophistication, the jumpsuit is your ultimate go-to. No longer just a casual alternative, the jumpsuit has evolved into an icon of modern elegance, making it the perfect piece for both laid-back and formal wedding celebrations. Amazon offers an impressive array of fancy jumpsuits that are as comfortable as they are stylish—crafted from soft fabrics that move with you, yet are structured enough to maintain a flattering silhouette. Whether you choose a tailored piece for a formal wedding or a more relaxed, flowy design for a beachside celebration, these jumpsuits offer endless styling options. Pair these jumpsuits with a statement necklace and comfortable heels to add drama, or keep it understated with minimalist accessories and a chic clutch. Either way, you’ll look effortlessly sophisticated—and of course, ready to celebrate the special couple.
