Bathing Suit sizing: model is 2.5 and is wearing the 3. As you can see, she has plenty of room to grow and our size 3 should fit children until they are 4. All children are different but we recommend ordering true to size. #rodeodriveruffle #beaufortbonnet #pinckneypinkstripe #rodeodrive #dcmoments #beverlyhillshotelinspired 🌴
