What size is considered “plus size”?
The term “plus size” is used to indicate clothing sizes that are above the standard or average range. While there is no universally defined “rule”, plus size generally refers to sizes 14 and above in the United States.
However, the definition of plus size may vary between countries, brands, and fashion industry standards. In the UK, for example, a plus-size woman is generally UK size 12 or above. For the sake of this article, we are featuring brands that offer clothing over a size XL.
Who makes the highest quality plus size clothing?
There are loads of sustainable plus size clothing brands ready to outfit us with high quality plus size clothing from day to night. Universal Standard, Altar, The Standard Stitch, House Of Stone, and Big Bud Press are only a few companies that deserve to be on your radar. Have a look at our curated list below for even more amazing brands!
Who is the most size inclusive brand in the slow fashion world?
While there are many size-inclusive brands out there, Smart Glamour, Loud Bodies, Universal Standard, and On The Plus Side are by far the most sustainable plus-size clothing brands in 2026. For reference, Smart Glamour goes up to 15XL. How cool is that?
Are more sustainable brands going to increase their size range?
Finding stylish and high quality plus size clothing used to be an impossible task; however, in 2026, more and more sustainable fashion brands are striving to increase their size range.
As the fashion industry becomes more aware of the importance of diversity and inclusivity, many sustainable brands are recognizing the need to cater to a broader range of body types. So yes, more companies will join the size-inclusivity movement very soon.
