Pink Chicken Jennifer Dress in Birthday Buddies Print. Festive flair for a special day! An animal-themed "Birthday Buddies" print enlivens our Girls' Jennifer Dress, designed in 100% cotton. This print is a collaboration with Berlin-based illustration and print artist Berry Aktuglu. Ruffled trim enhances the look as a feminine finishing touch and pairs perfectly with the matching Baby Jennifer Bubble Romper for a coordinated Big Sister/Little Sister look.
