If you’re short, stick to a two-button jacket—it’s the most elongating on your torso. Make sure your jacket ends 4 to 5 inches below your hip and ask for no break in the trousers so you look taller.
Color is also important. You should wear a medium to dark suit instead of a sport coat and trousers, because the single color from head to toe will help elongate your body.
If you have a stocky torso, skip big, bold patterns like windowpane and houndstooth and go with vertical pinstripes instead. They’ll draw the eye up and down instead of side to side.
Two-button suits will also highlight your shoulders and lengthen your torso, helping you look slimmer instantly.
The trend in men’s suiting is veering toward wider lapels again. Stick with a narrow or standard lapel—no wider than 2.5 inches—so it’s in proportion with your frame.
We also like a double-breasted fit for slim guys, since layering on fabric adds bulk. In this case, that’s a good thing because it adds heft to your frame.
Tall guys should opt for a three-button jacket. The third button is appropriate for your height—unlike a two-button suit, which will elongate your frame even more.
But avoid cropped jacket and pants. This trend looks great on guys of average height, but on you, it will look like you outgrew your suit.
