Merino Wool Blend Moto Jacket | Loft Another great find for big busts. Great weight to this jacket and versatile ways to wear it . . . zipped all the way, partially, or not at all. I'm a 34GG, and when I zip the size L all the way, it does not give me the smashed boob look. Neither did the size M, but I preferred the length of the L on me.
