This is a short-sleeved romper (70cm) from Akachan Honpo. It has a marine pattern and is made of a polo shirt-like fabric, making it look very cute like sportswear when worn ♡ (lol) The buttons are two-hole buttons, not snap buttons. My child looked uncomfortable with the top button fastened, so I left it open. It has been used regularly for several months, so there is some wear and tear, but no noticeable yellowing or stains. *Please refrain from purchasing if you have allergies, as we have a cat.
