Navy button-up romper, for 3-6 months, with fleece lining. ▶ Although it's difficult to keep babies warm at this age, the outer material is brushed (sweatshirt) fabric and the inside is fleece-lined. The cuffs and ankles are gathered, so I think this one piece will keep your baby warm. The crotch has snap buttons, making diaper changes easy. Also, the button details, the paneling, and the pockets show a lot of attention to detail for clothing of this age, and I think it's stylish. - Brand: baby GAP - Size: 3-6 months - Color: Navy - Design: Button-up romper - Features: With pockets Selling because my baby has outgrown it. It's in good condition. Thank you for looking.
