Founded by mother and designer Laura Sellers, Seaside Proper creates fine children's clothing rooted in the belief that every child is uniquely made. Each piece is thoughtfully designed and crafted with the same care, intention, and individuality.

Our In-House Collection is sewn in the United States by our small sewing team, with exceptional quality and attention to detail from start to finish. Alongside it, our International Preorders are made with a trusted international manufacturing partner, which lets us offer beloved designs at a more accessible price.

Seaside Proper offers seasonal collections through limited presale releases, alongside Seaside Proper Trunk, our year-round collection of custom, cut-to-order pieces.

Uniquely designed. Thoughtfully made.
