But for all the times you want or need to buy something new for your little one, there are so many sustainable kids’ clothing brands on the market these days.

In 2020, entrepreneur and mother Louise Ulukaya founded Mon Coeur, is French for “my heart,” in an effort to create the most sustainable kids’ clothing brand possible.

Entrepreneur and MIT graduate Sadia Sharmin grew up in Bangladesh, where there is a huge fashion textile industry — making her acutely aware of the way outsourcing fashion manufacturing can harm unprotected workers and the environment. So, she founded Cotonly, a low-waste children’s clothing brand for kids ages 2 to 12. The brand makes all of its colorful and comfy clothing from organic cotton — including its fleece tights, which are typically made from synthetic materials.

Cotonly’s factories are GOTS and OEKO-TEX certified factories; the brand has also made efforts to reduce its design cycle and make all samples digitally, which reduces waste; and the company aims to have the “most ethical and sustainable manufacturing process” possible.

Winter Water Factory

Brooklyn-based company Winter Water Factory uses 100 percent certified organic cotton to make its kids’ clothing — and the brand’s entire product line is both designed and made in Brooklyn, N.Y. Even though most fashion companies outsource production to keep costs low, Winter Water Factory has managed to keep its design and manufacturing process local, while keeping prices fair, compared to other domestically-produced brands.

Winter Water Factory makes a wide variety of styles for kids and babies, from bibs to baby gowns to onesies to matching sweatsuits. Items come in sizes ranging from 0M (newborns) to kids’ size 10, and the brand makes adult items as well.
