This is a set item from Earth Music & Ecology, consisting of a French cardigan with buttons and a tank top. The French sleeves, which make the shoulders look elegant, are a key feature. The walnut buttons also give a refined impression. The inner tank top has a ribbed design that makes it look sleek, which is another appealing point. I think you can enjoy wearing them both as a set and separately. I have kept it in the closet since I bought it.
