Cardigan: 3-6 months Knit: 6-12 months Tights: 0-12 months The cardigan is labeled 3-6 months, but it was worn comfortably at 11 months (see image 6). All three items were worn from around 10 months to 1 year and 2 months. I think there is little wear and tear on the fabric. Please check the photos for the condition.
