DUVETICA Reversible Boa Down Vest Size: 40 Actual Size: Shoulder width 38cm, Body width 46cm, Length 56cm Please understand that there may be some errors due to amateur measurements. The size is the outer measurement. The boa has thickness and is fluffy, so please consider it to be 2-3 cm smaller than the outer measurement. I purchased it from a local select shop, so please rest assured. It is a very beautiful item, only tried on after purchase. It is an item that costs 72,600 yen including tax. Thank you.
