This is a set-up from the Australian brand 【Seed】, which is not available in Japan. It's a beautiful item purchased in Singapore. It's 100% cotton. It has a blue, white, and orange check pattern. The shirt is size 4 (approximately 115cm), and the pants are size 3 (approximately 105cm). I bought the shirt a bit larger because I wanted an oversized look. It's cute as a set-up, and also as separate pieces. I bought it for going out, but I didn't get to use it much this summer. The total cost was over 10,000 yen, but I'm sadly selling it because I think my child will outgrow it next year. Thank you for looking.
