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.

Every garment is made in-house in the United States by our small sewing team, ensuring exceptional quality, consistency, and attention to detail from start to finish.

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.
