The chest opening is part of the design and doesn't actually open. From the chest to the hem, excluding the shoulder straps, is approximately 113 cm. The pants are wide and voluminous, but the fabric is thin, so it shouldn't feel too heavy. It might be nice to wear it casually over a swimsuit, but be careful as it's see-through if you wear it with just underwear. The gathering on the chest and the gathering on the patch pockets on both sides are cute. Brand new, unused, with tags. - Material: 100% cotton - Size: L Thank you for viewing.
