Most listings target 18-inch dolls; some specify a 16–18 inch fit range. In short, these gymnastics outfits are intended for dolls about 16–18 inches tall—check the product description to confirm fit.
Age recommendations vary by listing—many products specify either 3 years and up or 5 years and up. Always check the specific product page for the seller's age guidance before purchasing.
One listing explicitly states "Spot or Wipe Clean," but most product details don't specify care instructions. Check the product page and any sewn-in care label; if no instructions are provided, spot-cleaning delicate pieces is a safe option.
