Our Top Ten Favorite Size Inclusive AND Sustainable Clothing Brands

Laude the Label is slow fashion and size inclusive

Slow fashion and size inclusivity are both fashion movements that have been rapidly gaining momentum, and yet they've typically been mutually exclusive. As sustainable clothing brands have been gaining a larger customer base and growing in size and scope, their size offerings have not always been growing alongside them. The majority of sustainable clothing companies do not offer above a size 12, despite the average woman in the United States wearing a size 14. "Plus-size" is typically considered to be a size 14 and up, and yet that size represents the average customer? Make it make sense. 

When we started carrying apparel in our sustainable shop almost three years ago, I struggled to find sustainable brands that offered inclusive sizing, and set out to figure out why this is. Through my research, I discovered that while brands often refer to larger sizes as "extended sizing", this is actually a bit of a misnomer, because creating larger sizes means developing entirely new collections. Clothing designs are typically based on a size 4, with inches added or subtracted from there, and "pieces for extended sizing need separate fittings, patterns, and design changes." In addition to requiring additional time, developing plus sizes often entails an additional cost related to the cost of using more fabric in each piece. Many sustainable clothing brands are extremely small, and these independently-run companies don't always have the resources to develop extended sizing at the pace with which us consumers would like. 

It is our firm belief that ethical fashion and sustainable fashion must be accessible to everyone who want to engage with it, because otherwise it is not truly sustainable. If the slow fashion movement is to survive and thrive amongst the hordes of fast fashion companies and fast fashion customers, it needs to embrace people of all body types. At Thread Spun, we do carry a limited amount of extended sizing options and continue to engage with brands we currently carry to advocate for extended sizing, but we are looking forward to a future where we can offer the same sustainable clothing options for all bodies. Plus-size customers have reported to us that as they don't typically see their sizing represented in boutique shops, they tend to shy away from them. This really stuck with me and it is my goal to prioritize changing this, at least at our little sustainable boutique. In the meantime, please know that we are always happy to reach out to brands we carry about securing additional sizing, and offer a 15% discount on extended sizes if they are available and we do not offer them in store (this does not apply to larger sizes that have sold out). And if we can't help you, the ten size inclusive and sustainable brands listed below certainly can! Hooray for inclusivity AND sustainability.
