When a baby arrives, it’s natural to want to dress them in stylish clothes. But outfitting newborns with trendy clothing can be more than just an effort to impress relatives. The right mix-and-match pieces can help develop a baby’s esthetic taste while keeping them comfortable for the most crucial developmental stages.

While there are plenty of online stores that cater to moms with babies in tow, some brands stand out for their fashionable and sustainable offerings. Monica + Andy, for instance, uses the softest GOTS-certified organic cotton (the highest standards of ethical manufacturing) to craft bold basics elevated in tons of aw-worthy prints and patterns. From kimono-style rompers and traditional envelope-neck bodysuits to modern layette sets, the label offers a little something for everyone.

In spring and summer, look for onesies in bright pinks and blues that add a pop of color to any ensemble. Floral print rompers and tees offer another fun option. And don’t forget to stock up on neutral hues like gray and black, which are perfect for pairing with patterned onesies and joggers.

Other baby clothing brands are taking inspiration from popular social movements and other trends to create fashion-forward styles. For example, one-of-a-kind custom designs can feature tattoo-inspired motifs and punk-style contrast colors. These styles are especially popular in the market for girls, but parents can find similar tees and dresses in boys’ sizes, too.

Baby clothing brands like Kyte Baby and Little Sleepies offer a variety of designs, including those that feature characters from favorite TV shows and movies. GH experts say that these clothes are aspirational, and they often come with high prices. But if you’re looking for a budget-friendly option, Old Navy has a great selection of bodysuits and dresses at reasonable prices—even before you factor in their epic sales.

Aside from being eco-friendly, a growing number of parents are choosing to buy organic baby clothes. These products are free from harmful chemicals and pesticides, which can seep into the skin. This helps reduce the risk of rashes, allergies and other health issues associated with conventional fabrics.

The best part of this trend is that the clothes still look and feel just as good as their non-organic counterparts. And many are made in the USA, which helps ensure that they’re not sourced from sweatshops in developing countries.

For a mix of organic and non-organic options, consider shopping at Spearmint Love. This online store offers a wide range of labels, from Oeuf and Rylee and Cru to Wolf & Rita and its own in-house collection. The retailer also carries a selection of gender neutral styles that can be worn by both girls and boys, and the company is partnered with charitable organizations to give back.

Another great option is Cloud Island, which specializes in a wide range of breathable fabrics that are made using renewable energy. GH experts say that the brand’s knit cotton jersey is soft and stretchy, with one describing its stretchiness as “like nothing else she has in her baby’s closet.” The company also features a kaleidoscope of solid colors, so it’s easy to find mix-and-match wardrobe staples for both boys and girls.
