This design looks like a shirt layered with a vest. The relaxed fit allows for comfortable wear even with a growing belly. Although it's difficult to see in the photos, the inner fabric is split in the middle, allowing for breastfeeding. It seems like it can also be used as nursing wear after childbirth. *Please refer to the 7th photo. Shoulder width: 40 Body width: 42 Length: 72 Sleeve length: 28 The size is measured with the garment laid flat, but measurements are taken by a non-professional, so there may be slight differences from the actual size. Please understand. Thank you for viewing.
