Weddings are a time for celebration. You get to reunite with friends and family, witness the love between those dear to you, and party the night away. 

However, while weddings are a joyous occasion, knowing what to wear as a wedding guest can be pretty daunting. Not only do you have to think about the dress code and venue, but you also have to choose an outfit that flatters you without taking attention away from the bridal gown.

That’s why today, we’ll use our expert eye to help you find the perfect outfit for a formal wedding. We’ll also share some styling tips and outfit ideas to get you started, as well as some curated picks from the new Sherri Hill collection.

What Do You Wear to a Formal Wedding as a Guest? Formal Dress Code Basics

A formal dress code means ditching the sweaters, sandals, and jeans. It’s a more sophisticated version of a cocktail dress code, and your outfit should have a refined flair and appear well-fitted. Common formal attire includes maxi-length dresses, tuxedo suits, stiletto heels, and tailored blazers.

Be mindful that a formal dress code isn’t the same as a black tie dress code, which calls for full-length ball gowns and black dinner jackets. If you’re curious about attire for this dress code, take a look at our guide on what to wear to a black tie wedding

A formal dress code offers more room for flexibility than the ultra-formal black tie dress code. This means you can opt for bolder colors, printed dresses, and flats, provided your outfit is still polished.

Formal Wedding Outfit Ideas for Women

Below, we’ve gathered some of our favorite formal wedding outfit ideas. They offer that perfect blend of sophistication and comfort that’s still more elevated than what to wear to a semi-formal wedding. 

  • A-Line Ruffled Dress: An A-line ruffled dress is playful, feminine, and romantic. You can keep the look subtle with ruffles on the bodice or sleeves, or go for a more showstopping look with a ruffled skirt. 
  • Satin Drape Dress: A satin dress with a drape cut is modern and universally flattering. Pair with a matching clutch bag to catch the eyes of other guests without stealing the spotlight from the bride.
  • Floral Maxi Dress: A floral maxi dress won’t just keep you cool at a summer wedding; the style is also sure to accentuate your natural beauty and offer a whimsical yet elegant vibe that very few dress styles can match. 
  • Asymmetrical Maxi Dress: An asymmetrical cut is a great way to express your creative side while keeping in line with the formal theme. You can elevate the look further by pairing the dress with contrasting jewelry. 
  • Sleek Tailored Jumpsuit: A jumpsuit is effortlessly chic and will allow you to dance the night away. Stick to a tailored fit to keep your look in line with the formal dress code, and pair with black heels. 

Formal Wedding Outfit Ideas for Men

Now for the Gents! Here are some staple outfit ideas that are sure to suit the formal occasion:

  • A slim-fit suit with a white shirt and brogues for a classic look. Stick to neutral shades such as navy, gray, and beige. 
  • A charcoal gray suit with a sophisticated wristwatch and embellished cufflinks.
  • A burnt orange suit with a pair of leather dress shoes. Ideal for the fall season.
  • A three-piece wool suit to keep you snug and stylish in the winter months.

What Not to Wear at a Formal Wedding

As a guest at a formal wedding, don’t wear anything that doesn’t fit the formal bill. You’ll also want to avoid white or off-white colors like cream, nude, and ivory. Likewise, avoid wearing light colors like pastel yellow and pale blue. While these colors may not draw eyes in person, when photographed, they often become washed out and appear white.

As a wedding guest, you also usually want to avoid wearing the same colors as the bridesmaids' dresses and other members of the wedding party, like family. This prevents awkward mix-ups on the day and ensures the bridal party will stand out in the wedding photos. 

Usually, the wedding color palette and any other important information will be detailed in your invitation. However, if you can’t find anything specifically mentioned, take a close look at the actual design of the wedding invite. You can usually find stylistic nods to the color or theme in its design. 

When in doubt, don’t be afraid to reach out to the wedding organizers directly and ask for clarification regarding party colors, wedding theme, or dress code. 

What Colors Are Too Flashy for Formal Weddings?

Neon brights or super bold shades of red, orange, or yellow tend to be a little much for a formal atmosphere. However, you can go with muted versions of any of these colors and fit in just fine. 

Formal Accessory Ideas for a Wedding Outfit

If you’re attending a formal wedding, your clothing is just the start. There are a few other things to remember to ensure you’re not too underdressed on the day.

Shoes  

A formal wedding calls for a sophisticated pair of shoes that’ll help tie the overall look together. However, be sure to prioritize your comfort, too; you’ll likely be on your feet the whole day and doing a whole lot of dancing!

If you’re not comfortable with stiletto heels, consider a low, thick heel instead, such as a wedge or block heel. You can also opt for a wide fit to give your feet more breathing room and keep those pesky blisters away. 

If you struggle with heels, a pair of pointed-toe flats is usually a safe option since they’re comfortable yet still provide that dressy, sophisticated vibe. 

Other Formal Outfit Accessories

Accessories can help tie your look together and allow you to express your personality. You can elevate your look with a sophisticated belt, clutch bag, silver earrings, or a pendant necklace. 

Just make sure that your natural features remain the focus; too many accessories can overwhelm your outfit and ruin the overall look.

Formal Outfit Ideas for a Wedding Frequently Asked Questions

Do you still have questions about dressing for formal weddings? Don’t worry; below, we answer some of the most common questions wedding guests still have. 

Does the Venue Help You Know What to Wear at a Formal Wedding? 

Yes, the venue can be a huge hint on how formal the dress code is going to be, and thus, what to wear at the wedding. 

If the venue is a luxury hotel and involves a five-course wedding dinner, you’re going to want to err on the “black tie” side of formal. However, if the ceremony is held outside and there’s a slightly more boho feel, you can probably get away with strappy, low heels for shoes. You may also be able to experiment with floral patterns or playful ruffles.

What Is the Most Formal Color for a Wedding? 

Black and navy, and very deep shades of green or purple, are the most formal colors for a wedding. 

How Do You Choose What to Wear to a Formal Summer Wedding? 

Formal summer weddings are going to be similar to formal weddings at any time of year, you just want to keep fabric choice in mind. Opt for lightweight, breathable materials like chiffon to ensure you’re comfortable and don’t overheat throughout the day. Make sure to check the weather forecast before the big day, too.
