Christening gowns should be beautiful and made with the best fabric and laces, but not detract from the true masterpiece, the baby. It is the baby that is being dedicated and at the same time that is who friends and family have come to see.
For a truely special gown, check to see if anyone in the family has a wedding dress that will never be worn again. If the fabric is not suitable, some of the lace might be just what the gown needs. And last but not least, pass the gown around with love and give it a family history.
