Materials vary by option: many toddler sets are 100% polyester (including polyester fleece), some toddler options use a 95% polyester / 5% spandex blend, and some listings reference microfiber.
Sizes include toddler options shown in titles (examples: 2T–5T) and women's sizing for adult short-and-top sets listed as XS–3X.
Fit is influenced by regular vs. relaxed fit labels, elastic waistbands (some listings note a 1-inch elastic), pull-on bottoms, and ribbed cuffs on some toddler sets.
Designs typically show a character face on the top with matching tossed or all-over prints on the bottoms that include faces, cookie accents, and playful text.
Bottoms are pull-on with elastic waistbands; some adult shorts also include a tie plus an elastic-stretch waistband for a snug fit.
Necklines are listed as round or crewneck, and fits are described as regular or relaxed depending on the listing.
