Here, 20 fabulous party-ready dresses none of which cost more than $100, so you can focus on celebrating your loved ones and not fretting over your credit card bill.

express black affordable wedding guest dresses

1. Express Satin Open-back Midi Dress

Most Versatile

This simple black midi can be made to work for just about every dress code or season with the aid of the right accessories, and the open back adds a bit of sex appeal without being too much (we don’t want to scandalize grandma). Basically, a perfect LBD.

Size range: XXS to XL

2. Lulus Molinetto Lace Maxi Dress

Best for Black Tie

You don’t need to spend a ton to find a fancy gown that will fit right in at a black-tie event. This tiered lace number will look gorgeous twirling on the dance floor, and looks just as beautiful with simple black shoes and pearl studs as it does with a glittering statement necklace and matching silver heels. And according to reviews, the length works well on both shorter and taller women.

Size range: XXS to 3X

3. Cupshe Ramla One-shoulder Dress

Best for Cocktail

We’re so glad this satin frock comes in so many different colors (eight to be exact) because we want to wear it to basically every cocktail party from now to 2027. The ruching at the waist helps create the illusion of an itty-bitty middle and the top is super flattering for just about any cup size. Oh, and did we mention it’s machine washable?

Size range: S to XL

reformation affordable wedding guest dresses

4. Reformation Rou Knit Dress

Best for Dressy Casual

Dressy casual is a tough dress code to plan for as you don’t want to go too casual nor do you want to show everyone up in something too formal. The easiest solution? An elegant little black dress worn with some classic accessories, like strappy heels, a pearl necklace or some diamond studs.

Size range: XS to XL

astr the label affordable wedding guest dresses

5. Astr The Label Gaia Dress

Trendiest Color

Barbie pink dresses are everywhere right now, but we especially adore this cowl-neck slip for its easy elegance. It also features a crisscrossed back that’s fully adjustable so you can choose exactly how much cleavage you’re comfortable showing. While most reviewers say the Gaia dress runs true to size, some suggest going down a size if you prefer a fitted look.

Size range: XS to XL

Petal + Pup

6. Petal + Pup Andean Side Cut-out Midi

Trendiest Silhouette

Cutouts are having a pretty major moment right now but can often look far too sexy for a wedding. This jersey midi, however, shows just the right amount of skin, and could even be adjusted to be smaller thanks to the drawstring ties. All you need are some gold statement earrings and simple black strappy sandals and you’ll be all set.

Size range: S to L

cupshe affordable wedding guest dresses

7. Cupshe Tea-length Floral Dress

Most Budget-Friendly

None of the other guests will believe your floral midi costs less than 35 bucks. Plus, the navy design can be made to work for spring, summer or fall and can be dressed up or down for multiple types of dress codes, meaning you’ll get even more use out of your budget-friendly score.

Size range: XS to XL

eloquii mini affordable wedding guest dresses

8. Eloquii Halter Mini Dress

Best Minidress

This flirty mini also comes in a marigold hue, but we’re partial to the icy lilac above. The A-line silhouette is just flippy enough to move beautifully while you dance without running the risk of a Marylin Monroe moment. One thing to note on sizing: According to reviews, the bust runs a little small, so you may want to size up to accommodate a larger chest.

Size range: 14 to 28

cupshe floral midi affordable wedding guest dresses

9. Cupshe Floral Slip Dress

Best for Spring

Spring weather can be fickle—one day it’s sunny and warm, the next it’s raining and chilly—but this midi will keep you comfortable no matter what Mother Nature has in store. The back also has an adjustable tie so you can better fit the bust to your figure.

Size range: XS to XL

jcrew affordable wedding guest dresses

10. J.crew One-shoulder Linen Dress

Best for Summer

This linen mini is super breathable to combat hot, humid weather in style, and is also fully lined so you don’t have to worry about your undergarments showing through. The silhouette is just the right balance between loose and fitted, maintaining some semblance of a figure without the material clinging to you and showing sweat marks all the faster.

Size range: XXS to 3X

petal pup satin affordable wedding guest dresses
Petal + Pup

11. Petal + Pup Luella Dress

Best for Fall

This one-shoulder twist on a classic slip dress is one of Petal + Pup’s best-selling styles. The ruching at the waist is incredibly flattering and great for masking that post Champagne toast bloat. Some reviewers suggest it runs a little large, so we suggest double checking the size chart before you order, just to make sure.

Size range: 0 to 12

asos curve affordable wedding guest dresses

12. Asos Curve Pleated Midi Dress

Best for Winter

Stand out from the inevitable sea of black frocks with this stunning deep blue embroidered number. And we love that we can wear a regular ‘ol T-shirt bra instead of a strapless. Many reviewers mention the neckline being a little low, but there is also amble fabric to pin or sew it up a bit higher it you want a more modest look.

Size range: 12 to 26

eloquii yellow affordable wedding guest dresses

13. Eloquii Ruched One-shoulder Dress

Worth the Splurge

This one-shoulder number is surprisingly sexy and the ruched material looks stunning on figures of all types. The dress is also fully lined, so you don’t have to stress over your undergarments. You can also adjust the ruching to make it a little shorter or longer to hit right where you need it to.

Size range: 14 to 28

asos affordable wedding guest dresses

14. Asos Maxi Tea Dress

Best for a Garden Party

Don’t let all those colorful blooms show you up. The light green color of this backless gown works for just about every skin tone, and the button detail in front adds a sweet touch that’s also practical—the buttons can be undone to show more leg if you want.

Size range: 0 to 14

Abercrombie & Fitch

15. Abercrombie & Fitch Smocked Puff-sleeve Midi Dress

Most Comfortable

We came for the dainty floral print but stayed for the incredibly comfy smocked design on this knee-length frock. The sleeves can also be pulled down for an off-the-shoulder neckline if you prefer.

Size range: XXS to XL

express mini affordable wedding guest dresses

16. Express Satin Pleated Mini Dress

Best Bra-Friendly

For those who loathe strapless bras and would rather not go braless either, this mini with an asymmetrical hem can be worn with your favorite T-shirt bra. The material is even thick enough that you don’t need to bother searching for nude bras or panties. Plus, we love the ‘80s-inspired pleating for a vintage nod that isn’t too on the nose.

Size range: XXS to XL, also Petite

asos navy slip affordable wedding guest dresses

17. Asos One-shoulder Satin Dress

Best Slip Dress

There are plenty of classic slip-dress silhouettes out there, but we actually prefer this one-shoulder design for an unexpected twist on the ‘90s style. It’s sexy, simple and ready for a spin on the dance floor.

Size range: 0 to 14

lulus strapless affordable wedding guest dresses

18. Lulus Satin Floral Jacquard Strapless Dress

Best Strapless

The jacquard material of this strapless number has a slight shimmer in the floral design, making it feel even more special, even without the addition of glittering jewelry. Reviewers suggest it mostly runs true to size, but if you’re between sizes we suggest going for the larger to better accommodate your hips and rear while sitting.

Size range: XS to XL

topshop affordable wedding guest dresses

19. Topshop Floral Halter Dress

Best Boho Style

Don’t let the tent-silhouette fool you—the open back on this halter adds a touch of sexiness to prevent you from looking totally shapeless. And because it has a high neckline, all you need are some fun drop earrings to complete your look (and a pair of colorful sandals, of course).

Size range: 0 to 14

20. More To Come Jaliyah Ruched Mini Dress

Editor’s Choice

PureWow’s fashion editor Abby H. recently wore this mini to a cocktail wedding reception with the sleeves pulled down for an off-the-shoulder silhouette. “I got so many compliments on this little cutie and it was also surprisingly comfortable. I will say, however, it runs small and there is little to no stretch. I sized up when I ordered and I am very glad I did”

Size range: XXS to XL
