To bring up your V Taper, you need to tighten your midsection and widen your back. Broad shoulders will make a "T", not a "V". To make it a "V", do a full range of motion with one arm dumbbell rows letting the dumbbell stretch out your lats as you lower it to the floor. Also, do wide grip pull ups for pronounced width. But that's not everything. You need to watch your diet and do cardio to burn the fat so your midsection looks tiny compared to your lats.
