Tank Style Dresses run very true to size. The tanks are ribbed so they will stretch or conform to the shape of your child. There is a Dodgers heart applique on the chest of dress. Tank dresses start at 6mo through 12/14. Onesie dresses available NB - 12mo (please contact me for a custom listing for this item.) Please do not hesitate to message me for any questions on what size would be best for you. All of my items are handmade upon receiving your order.
