But what are these flowers that have grown on the pinkish ecru background of this terry cotton and polyester jersey bloomer? Little pink flower hearts, of course! We love the soft, fluffy and comfortable blend of cotton and polyester. The polyester, added to the cotton in very small quantities, gives the fabric exceptional elasticity and prevents creasing. A little bloomer with an elasticated waistband and thighs. Paired with a T-shirt or a little blouse, your babies will be the cutest when out and about in town, in the countryside or on the beach.
