rb Miramar for the whole family. Introducing Mini rb Miramar, a new collection of kids' clothing featuring our revolutionary printing technique that makes any material resemble denim. Based on our bestselling rb Miramar track pants, this children's pair is made from breathable cotton terry fabric that's ultra-soft on the inside and printed on the outside to look like jeans with vibrant side stripes. A pull-on elastic waistband, wide leg, and digitally printed denim details ensure your little one will love how they fit and feel (just as you'll love that they're machine washable).
