Thank you for viewing. This is a free-size付け襟 (つけ襟 - detachable collar). It's sized for people with a height of 100cm to 160cm. The neck area is roomy, so even adults up to around 160cm can wear it without issue. I think it would look cute paired with your light blue or white cardigans, dresses, or pajamas♪ ◎ Hairband available for ¥1700 ※ We have gowns & dresses for 80cm children available, so please contact us in the comment section if you're interested.
