On the hunt for the perfect wedding guest style? Look no further than the midi wedding guest dress. Midi dresses are notoriously versatile - their shorter length makes them ideal for spring and summer weddings, while they work just as well in colder months with a stylish cover-up. Plus, they give everyone a better glimpse of your shoes (always a win) and are far more practical - no tripping hazards or sandy hems if you’re heading to a destination wedding.

That said, keep the wedding guest dress code in mind. While midi dresses are a top choice, more formal occasions - think black or white tie - might call for a full-length gown instead.

From bold blues and romantic florals to pretty pinks and elegant long sleeves, we’ve rounded up 20 of the best midi wedding guest dresses to shop now - guaranteed to get the couple’s seal of approval.

Considering a Midi Wedding Guest Dress? Here are our 20 Favourite Styles for Upcoming Celebrations: 

Blue Midi Wedding Guest Dresses

Blue is the perfect wedding guest colour, from bold cobalt-like shades to soft shades reminiscent of the sky on a summer's day - we simply can’t get enough! No matter what season your wedding invite sits in, we’re here to help you find the perfect gown.

Head to ASOS for a rich and elegant blue midi wedding guest dress, featuring a trendy square neckline and contemporary thigh split. Otherwise, for something more summery - ideal for garden party weddings - we adore this one-shoulder Nobody’s Child dress in a paler variation. 

Pink Midi Wedding Guest Dresses

Pink is a shade that never goes out of style, and for good reason. It’s eternally elegant and ultra-feminine, perfectly complementing a range of complexions. Whether you want something full-skirted and statement or a dress that embodies the epitome of spring and summer - complete with some eternally-trending ruffles - you’re in the right place for the best pink midi wedding guest dresses.

New Look and Club L London know a thing or two about providing this season’s hottest looks on a budget, and starting from just £32, nothing’s stopping you from looking pretty in pink on the big day. 

Long Sleeve Midi Wedding Guest Dresses

While a shorter length might feel more appealing, there’s nothing wrong with balancing that out by opting for a long-sleeved wedding guest dress. Midi dresses with sleeves can feel just as summery, and are often perfect for taking you from day to night, fending off the evening chill without the need for a jacket.

Despite the long sleeves, these selections are perfect for the warmer months. They’re free-flowing, featuring mesh sleeves or thigh slits to ensure you don’t feel too covered up. Interested? Head to Nobody’s Child or Pretty Lavish for the best long sleeve midi wedding guest dresses. 

Floral Midi Wedding Guest Dresses

While florals for spring might feel tired and somewhat done, who said florals are just for spring? If you’ve spotted a stunning botanical frock, you’ll want to wear it more than just one season of the year. If you’ve been paying attention to trends, you’ll know that floral fashion has had somewhat of a makeover. Gone are the days of dated, prints - now you’ll find larger, more statement designs, ditsy prints or vintage-inspired flowery.

If florals have, and always will have, your heart - shop these looks from Mint Velvet and Club L London, where the ruffled design and halter neckline will flatter almost every body type. 

Green Midi Wedding Guest Dresses

While sage green is practically synonymous with weddings, you shouldn’t discount alternative shades of green, too! From soft sages to jewel-toned emerald dresses, ideal for winter and party season weddings, green is a go-to for a reason.

Whether you’re searching for an above-the-knee option or something closer to a midaxi length, we’ve left no stone unturned. From this elegant fluted-sleeve, chiffon gown from ASOS to the one-shoulder, statement bow option from Lavish Alice, green midi wedding guest dresses are a winner in our book. 

Summer Midi Wedding Guest Dresses

Attending a wedding during the summer months? Midi wedding guest dresses are an obvious choice. For most occasions, mini dresses typically don’t sit within the wedding-appropriate category, so midi dresses are the perfect way to opt for a shorter length.

Looking for the perfect summer midi wedding guest dress? Mint Velvet’s Palm Print Midi Dress may be neutral in shade, but its palm print gives it that effortless summer holiday feel. For a bolder take on the ultimate summer frock, New Look’s version brings vibrant energy to the mix.

Bardot Midi Wedding Guest Dresses

Whether you’re looking for a midi wedding guest dress because you might not be the tallest, or simply because maxi gowns aren’t your thing, Bardot midi wedding guest dresses are a stunning choice. Want to know why? Bardot dresses are a masterclass in flattery - they highlight the shoulders and collarbones, creating an elegant, elongated neckline. It’s all about balancing proportions, by drawing attention upward.

If a Bardot wedding guest dress is the look for you, head to Lavish Alice and Phase Eight for these colourful yet elegant styles. 

One Shoulder Midi Wedding Guest Dresses

For those who have been busy keeping up with trends, you’ll know that one-shoulder dresses and asymmetric necklines are taking over. There’s nothing like the possibility of being labelled “best dressed” at a wedding, and no one does a one shoulder or asymmetric neckline like Mango.

This time, both of our top picks come from Mango - and for good reason. Whether you're drawn to bold, statement-making details like this dramatic draped design or prefer the understated elegance of a sleek, ruched grey midi, Mango is the place to be. 

Red Midi Wedding Guest Dresses

While there’s some contention as to whether red is a colour wedding guests should wear at all, because it can be seen as attention-grabbing or even symbolically tied to past traditions, it ultimately comes down to the couple’s preferences and the formality of the event.

Managed to get the couple’s approval, and getting straight to shopping? Have your lady in red moment with these stunning red midi wedding guest dresses from Mint Velvet and River Island, where the trending drop waist, full skirts and 3d floral designs promise to take centre stage in the best way. 

Yellow Midi Wedding Guest Dresses

From bridal parties to wedding guests and even brides jumping on the bandwagon, yellow midi wedding guest dresses promise to be popular for celebrations this year, so why miss out?

It’s the perfect mixture of summery yet soft, and these dresses from Anthropologie and Nobody’s Child are no exception. From a waterfall of delicate ruffles to an elegant open-back with a statement bow - doubling up on trends has never looked better.
