I purchased this from the Rakuten store "Catch - Gymnastics Uniforms and School Uniforms." It's a set of two. I'm selling them because my child has outgrown them. Please check the cuffs for any pilling. The ribbed cuffs make it very easy to roll up the sleeves, and they were also very durable and easy to use.
