Stylish Fall Wedding Guest Dresses Under $100: Affordable Picks for Every Dress Code

Whether you're going to a simple, casual backyard fall wedding or heading to a black-tie fall formal, we've found some of the best fall dresses for wedding guests for nearly every dress code, all under $100. Here are 90 of our top picks, with more ideas for you by color and dress code.

Fall is the peak of wedding season in many parts of the country, and buying a new dress for every invitation adds up quickly. Cheap does not have to mean low quality, and keeping each dress under $100 makes it easier to say yes to all of the fall weddings on your calendar, from an October ceremony in a vineyard to a November destination wedding.

Affordable Wedding Guest Dresses in Top Fall Colors

Here are a few of the colors we love to see at fall weddings, with links to more dresses under $100 in each section. You can also use these guides to find affordable bridesmaid dresses in these colors!

Burgundy

Burgundy is the color most closely tied to fall weddings, and it flatters nearly every skin tone. A deep wine shade works in velvet, satin, or soft crepe, and it looks right at a casual ceremony and at a black-tie reception.

Teal

Teal sits between blue and green, which gives it the richness of a jewel tone and keeps it from reading as a summer color. It looks great against fall foliage and photographs well in both daylight and candlelit receptions.

Dark Green

Forest green, emerald, and olive are the greens to look for in the fall. They hold up well in satin and velvet, and they pair easily with gold jewelry.

Brown

Brown is an underrated color for fall weddings. Chocolate brown in a satin slip or a long-sleeve midi looks modern, and it works with warm metallics, black, and cream accessories.

Burnt Orange

Rust and burnt orange are one of the best colors for fall. They echo the turning leaves and pumpkins and seem to be one of the best colors to try for the season.

Look for burnt orange in solid satin or in a unique print, since both stand out in a room full of black and navy. See more ideas for orange dresses under $100. 

Gold

Gold and mustard shades are great options for outdoor weddings, where afternoon light brings out the warmth in the fabric. A metallic gold or sequin dress is the perfect choice for an evening reception.

Dresses Under $100 in Common Fall Wedding Dress Codes

Check the dress code on the invitation first. Fall adds a second question: whether the ceremony and reception are indoors or out. Here are some of the more common dress codes you'll see, with dress ideas under $100 for each one!

Casual Dress

A casual backyard or barn wedding is the easiest dress code to shop for. Wrap dresses, floral midis, and sweater dresses all work, and a block heel or a dressy flat will hold up better on grass than a stiletto.

Semi-Formal Dress

A semi-formal wedding is the dress code that most invitations land on. Knee-length or midi cocktail dresses are standard, and short dresses are fine as long as the fabric and fit look dressy.

Formal Dress

Formal weddings call for long dresses or an elegant midi in a dressy fabric. Formal dresses under $100 take more searching than casual styles, but satin, chiffon, and velvet versions are out there, especially from Lulus and Vici.

Black Tie

Black tie means a floor-length gown. It is the hardest dress code to meet on a tight budget, so look at sale sections and stick to one strong fabric, such as satin or velvet, instead of heavy beading.

How to Choose the Perfect Wedding Guest Dress for Fall

Finding the perfect dress for a fall wedding starts with the weather. A dress that works at a July wedding can look wrong in October, so these details matter most when you choose fall wedding guest dresses.

Sleeve Length and Fabric

While summer favors strapless and sleeveless dresses, adding a bit of coverage with short or long sleeves is a natural choice as you transition to fall style.  Three-quarter sleeves are another elegant length, a good middle ground for an indoor reception that runs warm.

We're also seeing a lot of wedding guest dresses with sheer cape overlays, which can be a great way to have a bit of coverage for the ceremony, then remove the cape for dancing at the reception. 

Prints for Fall

Floral print dresses are not just for a spring wedding. Fall floral patterns in rust, plum, and forest green look really rich and perfect for the season. Polka dots are a trend we're seeing more and more of, but since it's a bit of a retro style, it feels timeless.

A unique print is a good way to get plenty of compliments and also sometimes keeps you from wearing something that is similar to the wedding party. 

Fit and Comfort

You will be sitting through a ceremony, eating dinner, and spending time on the dance floor, and fall weddings tend to be a bit unpredictable as far as weather; comfort matters as much as the color. Again, more styles with a bit more coverage, like wrap styles or longer sleeves, are a great idea. 

What Not to Wear

We've said it many times before, but it's worth repeating. Avoid white, ivory, and anything close to them, since those shades are reserved for wedding dresses. Slightly sexy or revealing wedding guest dresses can work if it's a style that you know your fellow guests will be wearing, but keep it to one statement, such as a slit or a low back, cut-out, and not all at once. If you are headed to a destination wedding, then fall might be different there, so check the climate and the venue before you commit to fall styles and heavy fabrics.

Shoes and Accessories

We think a  block heel is the most practical choice for wedding guest heels for outdoor weddings, and we found a pair from DSW that was comfortable enough to wear all night. Skip anything you would not want to dance in. Accessories that are warm-toned, like gold or jewel tones, can be a great look with the fall dress colors.

Where to Shop for More Affordable Dresses for Weddings

You can almost always find a huge selection of fall wedding guest dresses under $100 on Amazon, but we did a try-on session a few years ago and didn't find the quality to be consistent across all the styles. We'll certainly include some of those dresses in the ideas for you, but for the most part, we love brands like Lulus, Petal & Pup, Vici,  Red Dress, and a few other brands like ASOS for wedding guest dresses under $100, because we've had the chance to see some of these dresses in person, and we know they stand up well. Seeing a dress in person is what separates quality dresses from the ones that only look good in a product photo.
