Heights vary by doll line, generally ranging from about 11.5 inches up to around 20 inches tall.

Recommended ages vary by product: common labels include 3 Years and Up, 4 Years and Up, 5 Years and Up, 6 Years and Up, and some collectible items are labeled for Adults.

Articulation varies across the selection: some dolls have no articulation (fixed pose), others are described as articulated or posable, and some feature 'Made-to-Move' or similar jointed bodies for more advanced posing.

Product listings commonly list plastic and polyester as the primary materials used for the dolls and their clothing/accessories.

Included items vary widely by set. Examples from listings include You Create kits that add interchangeable heads plus about four fashions and multiple styling accessories (e.g., 4 fashions + 8 styling accessories or 4 clothing pieces + 2 pairs of shoes + 6 styling accessories) and playsets that advertise 30+ accessory pieces.

Some dolls are designed to represent specific health conditions and neurodiversity: examples include type 1 diabetes features (insulin pump, continuous glucose monitor, medical tape and a phone showing a CGM app) and autism-related items (noise-canceling headphones, a working fidget spinner, an AAC-style tablet and flexible joints to support related play).
