Earlier this year Chris Brown promoted his “Dum English” toy collaboration with Ron English. And now it looks like he’s promoting a new line of clothes under the brand name Mechanical Dummy.  The singer took to his Instagram account to show off a windbreaker from the upcoming collection modeled by none other than himself and his girlfriend Karrueche. The streetwear pieces are available in a variety of colors, and will drop on the Mechanical Dummy website just in time for back-to-school shopping. What do you think of the line so far? [web.stagram]
