The big picture
Kids grow quickly, and the next size is always around the corner. These national figures put that everyday family rhythm in context: what households spend on apparel, how fast secondhand apparel is growing and where textiles go when they are no longer used.
These are national apparel and textile figures, not sales figures for Kiddy Korner. Every statistic links to the organization that published it, with the source date shown clearly.
