I found this Bootheel Trading Co. Halter Vest ($29, originally $48) for any gal who wants to embrace the Sgt. Pepper look in a sexier way than it was shown on the runway. The halter neck makes it playful, while the flap pockets and piping give it a unique appearance. A covered-up version can be achieved by wearing the vest over a tee, turtleneck, or a button-down shirt. Left, left, left, right, left . . .
