The Tiffany Baby Boys Muslin Crepe Shirt and Shorts Set in White is a two-piece baby boys' set from a muslin crepe fabric. The crepe weave gives this a slightly more textured, refined finish compared to standard muslin — making it a strong choice for occasions as well as everyday warm-weather wear. Light, breathable, and easy to put on, it works well for holidays, family gatherings, christenings, or summer days out.
