Materials vary by style: some women's sets are 100% cotton jersey; many adult/lounge sets use polyester-based stretchy blends; and a few kid sets list polyester with elastane.
Women's/adult sizes are offered in standard adult ranges (examples include S to 3X and single listings like Small, Large, 2X, 3X). Children's and toddler sizes use age-based or numeric sizing (examples include 2T and kids' sizes up to 14).
Care varies by set: many adult sets recommend machine wash and tumble dry; some kid sets recommend machine wash and line-dry or lay flat to dry; and certain printed lounge sets advise washing before wearing, using warm water, avoiding bleach, and gently ironing if needed.
Most pants are pull-on style with elastic waistbands—either full elastic or elastic with a functional drawstring. Some lounge styles include adjustable waistbands.
Examples include purple buffalo plaid, purple paisley, butterfly prints that combine purple and blue, tie-dye styles, and other fun printed designs.
For printed lounge sets: wash before wearing—use warm water, do not use bleach, and gently iron if needed to remove wrinkles.
