To me, the taper def isn't the problem. Remember Charly's post on the optimal silhuette for built guys? You want a good taper on your pants if you've got bigger thighs. A straight fit will make your legs look like tree-trunks and will make the bottom overpowering.
If anything, the rise is too low on those pants and the tee is too short. I've got a decent drop with a 42 chest, 32 waist and 34 hips, and I def look more balanced in terms of proportions when the tee goes over half of the bum and wear the pants low / longer rise. The problem with LB's pants is that they sort of carve in at the crotch due to the lower rise. You will get a better shape a la Snowman with pants with higher rise. A boot tuck can also help. Look at Charly and Snowman fits.
Also, wear darker pants as it has a slimming effect.
