This denim shirt is what I wore even when I was heavily pregnant (almost ready to give birth)! ٩(^‿^)۶ Of course, I couldn't button the ones around my belly anymore ^^; The buttons snap closed. There are also buttons near the elbows, so you can roll up the sleeves and secure them. ★ Approximate measurements when laid flat: Length: 67cm Width: 45cm Sleeve length: 63cm There's no size label, but I think it's a size S. The brand was written on a black tag, but it was hard to read and I couldn't tell.
