Serendipity is sold in complete sets. Serendipity girls clothing runs generous by about a full size so we recommend ordering true to size as this will already have plenty of growing room. Serendipity clothing is a customer favorite here at Everything But The Princess. Moms love the darling styles, loaded with so many details and girls love the fun designs. Serendipity clothing for girls is a great line for sisters to match or coordinate and we offer a large selection in sizing from baby, toddler to girls size 10. Moms love the sistering that Serendipity offers for their family pictures, special events and just everyday looks.
