Where can I buy this bolero/shrug that brooke wore in this episode?

I've been trying to 検索 for this 上, ページのトップへ but I seem to have a hard time since I don't even know how its called... so please help!?!
によって the way, there's a knitted version of this kind worn によって a chinese celebrity (i think?) but I forgot on which YouTube video I saw it... :(
