It is sounds silly, but when we talked about this Japanese brand called Mastermind we just can rolled our eyes. This beanie which Yesung was wearing costs about $929.00.
Well, to be honest, for me it's really a waste, since it's just a beanie (although it's made from black cashmere). I think Yesung is totally in love with this brand, you can see him in a lot of Mastermind items, it's easy to find out because their infamous skull logo.
Here is the link if you're interested enough to buy it.
P.S. You can buy the 'normal' beanie and sew the leather skull logo on it. VOILA~! The similar beanie will be yours. XD
