Websites such as ASOS, Simply Be and Next stock a range of curve labels like ARRANGE, Joanna Hope, YOURS and Friends Like These, as well as stocking their own plus size collections.
Occasionwear favourites like Phase Eight, RIXO and Reformation also have best-selling pieces in extended sizes, typically going up to sizes 26-28, while US label Azazie goes all the way up to a UK 34 with the option of some designs being made to measure.
Nail wedding guest dressing with our answers to your burning questions.
Online stores such as ASOS, Next and Simply Be stock a great range of design-led plus size wedding dresses, but you can also find curvy wedding guest dresses at the likes of Phase Eight and Marks & Spencer and – if budget allows – Marina Rinaldi, RIXO and Reformation.
Plus size bodies can look great in everything from minis to maxis, statement sleeves to strapless – it’s all about wearing what you feel confident in, in a cut that complements your curves. Midi dresses are ever-flattering on all body shapes and work well with most wedding dress codes – look for those with A-line skirts, wrap bodices or strategic ruching to create a balanced silhouette.
Plus size wedding guest dresses work in all colours! Let the dress code, style of wedding and season in which the couple are getting married guide your choice of colour when it comes to choosing your outfit, as well as the shades you feel most comfortable in.
If you usually rely on black to see you through formal occasions, dress up a perennially elegant black outfit with colourful, metallic or lighter-coloured accessories, including a jacket. Or how about a shot of chic navy for a winter wedding?
The biggest faux pas you can make is to wear white – or a colour that could look white in photographs – as a wedding guest. Unless the dress code asks for it, steer clear!
You’ll find plenty of plus size wedding guest attire for winter weddings in our edit above, including stylish curve jumpsuits and elegant maxis in shades of plum, navy, red and even black.
Yes, absolutely! Plus size wedding guests – and bodies of all sizes – can wear jumpsuits to a wedding. Tailored and chiffon jumpsuits make a chic alternative to dresses.
