When it comes to baby girl dresses, finding the perfect fit is essential to ensure both comfort and style. The dress shouldn't be too tight or restrictive so she can move around and play easily. Nor should it be too loose to help prevent tripping. In general, the length of the dress, whether for casual wear or more embellished baby girl party dresses, should fall just above or at the knee to allow for comfortable crawling and toddling. However, this will depend on the occasion. For example, baptism dresses for a baby girl are usually on the long and flowy side as babies are mostly held during the ceremony.
