31 best plus-size wedding guest dresses, approved by a curve model
Featured in this article
Summer weddings are pending and trying to source the best plus-size wedding guest dresses never gets any easier; take it from a plus-size model who has attended her fair share of nuptials, tried on a fair few occasion dresses and fought with a lot of shapewear in her lifetime.
I know I’m not the only one who has a mini panic when that wedding invite pops through the letterbox, your group chat with your best friends is popping off and it’s time to try scowl the world wide web to find something to suit your shape, whether a halterneck or cowl neck style, a drape dress or maybe something with short sleeves if its a beach wedding. All these thoughts are constantly running through your head because all your smaller peers already have their hen do outfits ready and their evening dresses sorted.
Well don’t fret, I’m here to help your find that perfect look to align into your friends theme for their big day and more importantly something that will be comfortable, stylish and memorable for you.
You don’t have to tell me twice that finding plus size clothing IRL stores for those of us whose sizes are above a UK 18 is something of a myth. It’s something I’ve campaigned for over the last decade, but on a positive note there are brands and independent designers pushing for inclusion and raising their size ranges for us.
Currently my favourite is ARRANGE from ASOS. A collection of high end designs and silhouettes for all. Think sequin midi dresses, a-line maxi dresses, asymmetric shapes, luxe jacquard blazers, ruched floral prints, long sleeve chiffon sleeves, ruffle party dresses, polka dot midaxi dresses and red carpet fits covered in the most beautiful embellishments. All available from size UK 18 - 30. Something we haven’t had access to in the plus-size industry, quite frankly ever.
We also have slow fashion brands such as Dorothy & Rose creating pastel linen embroidered balloon sleeve dresses made for summer weddings and independent designers like Kitty Joesph creating dopamine dressing pleated party dresses and wedding guest outfits for all sizes. Even looks for the mother of the bride.
We also have Rental sites such as By Rotation that now carry a range of plus size designs if you are looking for something to just wear the once, but us curve girls tend to keep hold of the treasured occasion pieces that fit us well (because often they are so difficult to find), so it's often slim pickings.
Whether you've got a country spring wedding in the united kingdom or a summer wedding on some gorgeous beach abroad, or you're shopping well in advance for an autumn wedding guest dress/winter wedding guest dress and embroidery, sparkles and disco sequins are already being thought about, keep scrolling.
Ahead you'll find the best wedding guest dresses that span far beyond just the usual black frocks we're steered towards, because you deserve to show your personality on this special day.

For me a silk halter dress is such a versatile piece to have in your wardrobe, a pair of strappy heels and embellished accessories for a wedding, and layered with a big mohair jumper and trainers for a weekend look in the spring. Get you a dress that can do both.

Why you can trust me:
As someone who has been in the plus size industry since the 2010s and tried on her fair share of occasion wear on set and whilst modelling e-comm, I feel I have pretty good inside knowledge on the brands who cater to curves, cater well and don't just upscale the sizes with no consideration for a plus size body.
How I tested the best plus size wedding guest dresses:
Quite a few of the dresses above are already in rotation in my wardrobe and have already been worn to summer events this year. The rest are brands I know and have loved for years. Everything from luxe to high street and individual designers. I have also made sure to include pieces with breathable materials, silhouettes to suit all and a variety of price points.
