The advice for pear-shaped women could be applied to pear-shaped men. The only difference is clothing options. From what I remember, and what I have done, pear-shaped figures should try a slightly higher waist-line with a straight seam in dark, neutral colors. The bulk of the jean, if any, should be towards the feet. With the top half, you'd want something fit - no baggy T's or, on the opposite scale, too tight T's. Adding a button up shirt, jacket, or vest (etc.) that squares the shoulders (shoulder padding, perhaps, if you're not that broad-shouldered). Also, using a scarf can detract from the middle, but that also depends on your style.
The best thing to do is try things on and see how they look. Even if you order online, most of the time you can return items for full price within a set time. Just my two cents worth. Good luck.
