The only real drawback of this costume that we have to mention is that it doesn’t keep you warm at all, so unless you’re inside at a Halloween party, we don’t recommend that you wear it outside while trick-or-treating, unless you want to catch your death of cold. Well, you don’t have to feel bad about dressing as the bag guy anymore, black widow costumes and you can go ahead and order your very own Cobra Kai kimono to wear this Halloween.
