The sets are offered in Small, Medium, Large, and X-Large. Underwear size ranges are Small (4–6), Medium (8–10), Large (12–14), and X-Large (16–18). Bralette sizes are listed as Small (4/6), Medium (7/8), Large (10/12), and X-Large (14/16).
Listings describe the fabric as an elastic blend of nylon and spandex (often labeled simply as “Elastic”), providing stretch and recovery for a snug, comfortable fit.
Both styles are designed to be slipped on: the underwear/boy shorts use pull‑on closures, and the bralettes use pullover construction (no hooks or clasps).
The bralettes feature a U‑neckline with elastic spaghetti straps, giving a cami‑like, beginner bralette shape.
Listings emphasize seamless construction, tagless/no‑tag comfort, non‑padded, wire‑free designs, and lightweight, breathable stretch fabrics for all‑day wear.
The products are marketed for kids and young teens—listed for little girls, big girls, tweens, and teens—and are sized as Kids.
Product details note they’re suitable for active use, specifically for girls who play sports, do gymnastics, and participate in other athletic activities.
Some listings feature cute elastic logo bands or jacquard band styling; overall, items use elastic nylon/spandex blends and logo‑style band details on certain pieces.
