For those who knew us first as Sisterly Swimwear, welcome to our next chapter. Since day one, we’ve been on a mission to make sustainable fashion accessible to everyone. Every piece we create is made from 100% pure flax linen, designed in New Zealand, and crafted with care in our trusted partner factories in China.
After working with factories in Canada, Bali, and Colombia, we discovered that China not only offers unparalleled expertise in linen production but also allows us to source directly from the world’s leading supplier. By partnering with these factories, we eliminate the need to ship linen across the globe before production, reducing carbon emissions and aligning with our commitment to sustainability.
At Olive & Oath, quality is non-negotiable. We are dedicated to creating garments that stand the test of time, ensuring they remain a cherished part of your wardrobe for years to come. Our factories are ethically certified and regularly audited to uphold the highest standards of worker safety and environmental practices. Additionally, all our products meet ROHS standards, guaranteeing they are free from harmful substances.
We are equally devoted to inclusivity, designing pieces that flatter and celebrate all body types. For our first run, we are offering sizes up to Bodacious as we refine and perfect our plus-size range.
At Olive & Oath, we craft products you’ll love while striving to create meaningful change in the industry. Thank you for being part of this journey with us.
