Brand Story

As a natural problem-solver and MIT graduate, Sadia Sharmin saw a need for high quality, sustainable clothing that her children would enjoy and that she could feel good about. She was tired of relying on cheap clothing that would barely last a few washes and recognized the environmental impact her choices had.

Reflecting on her youth and growing up in Bangladesh, she knew that how we dress and what we choose to buy plays a larger part in environmental sustainability than we fully appreciate.

The clothing she loved as a child held memories that couldn’t be replaced. A pair of jeans she admired from a cousin or an intricately detailed dress passed on from a sister. These were the clothes that she cherished and sought as she grew up.

Sadia founded Cotonly with the premise that clothing should be comfortable, colorful, and well-loved but designed to be handed down to the next generation.

Cotonly offers clothes that tell a story worth sharing. Rich organic textiles, bright colors, and classic designs ensure that children will love them on sight. The high quality fabric, timeless styles and durability ensure future generations will enjoy Cotonly for years to come.

Cotonly’s designs are meant to be well-loved, and yet durable enough to be passed onto future generations. Seeing a niece, nephew or family friend wearing an outfit that your own child wore is priceless. The memories that clothing can evoke are unique and timeless. In sharing clothing, we share stories of our childhood and delight in the simple pleasure of being together.


Cotonly offers clothes that are both beautiful and durable to ensure they hold up to the messiness of childhood and last for the next generation to enjoy. Cotonly uses an abbreviated design cycle to reduce waste and works exclusively with factories that are GOTS certified organic and Okeo-Tex standard 100 certified to ensure clothes are free of harmful dyes and chemicals.


Cotonly leverages the latest technology to ensure that its clothing designs and samples are 100% digitally produced. This unique approach streamlines the production cycle to reduce waste and conserve resources. It can take up to 2,700 liters of water to produce the cotton needed for a single t-shirt, so reducing the production cycle and eliminating waste is extremely important
