rb Miramar for the whole family. Mini rb Miramar is a collection of kids' clothing featuring our revolutionary printing technique that makes any material resemble denim. Based on one of our bestselling rb Miramar jogger 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. A pull-on elastic waistband, elastic leg openings, 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).
