EVERYTHING TO KNOW ABOUT

Organic Cotton

When it comes to the bras & panties we wear every day, comfort matters, but so does what they are made from. That’s why we created our Organic Cotton Collection, a thoughtfully designed range of essentials that combines softness, support and sustainability. From breathable bras to everyday panties and comfortable shapewear, each style is made with premium organic cotton chosen for its natural feel, durability and lower environmental impact.

In this blog, we’re answering the most common questions about our Organic Cotton collection and the innovative ideas behind it.

What makes Siella's Organic Cotton different?

Our Organic Cotton collection was designed to combine everyday comfort with consciously sourced materials and innovative technologies. Each piece is made to feel exceptionally soft, breathable and lightweight while supporting more responsible production and environmental practices.

Are your bras & panties fully organic cotton?

Many styles in the collection are made with organic cotton throughout the entire garment, like Organic Cotton No-Show and Organic Cotton Rib. This includes trims and finishing details like straps, underband and hook & eye closure. We took a thoughtful approach to every component possible, creating essentials that feel softer, more natural and gentler against the skin.

Why choose organic cotton?

Organic cotton is grown without harsh pesticides and chemicals, making it a better choice for both your skin and the environment. It’s naturally breathable, soft and comfortable for all-day wear, especially for intimate essentials worn closest to your body.

Which certifications do you have?

Our Organic Cotton fabric is GOTS, OCS & OEKO-TEX certified, cultivated without the use of harmful chemicals. These certifications ensure no harmful levels of substances like pesticides, heavy metals, formaldehyde or chemical dyes.

Certifications help verify that materials are sourced and processed according to recognized standards, giving you greater confidence in the quality, safety and sustainability of the products you wear.
