IENA AQUA Ribbed Box Silhouette Cardigan Color: Gray Size: Free Price: ¥24,200 (tax included) Purchased from the Baycrews official online store. Made of thick cashmere-blend wool knit, so it's incredibly warm. It's almost too warm to need a coat, so I haven't had many chances to wear it. I wore it once for a short time, had it dry cleaned, and have been storing it, so it's in excellent condition.
