The first area one should look at when purchasing a suit is the shoulder slope. Suit shoulders should have a slight natural slope to them. The natural size and shape of your shoulders will determine how much padding the suit will need to make you look good.
Secondly a man should look at the fit around the chest and waist. The suit jacket should be about two inches larger than the chest to allow for comfortable movement and the waist should be wide enough to make the stomach look flat.
The next next that should be considered is the actual style of the jacket. Men that are in great shape should wear suits that accentuate this and men who are in poor shape should wear suits that hide this fact. A good rule of thumb is that if you are fit, less is more.
The pants of a suit need to be tailored with the same detail that you find in the suit jacket. Pants should be the same exact measurement as the measurement you get when measuring around your waist.
Next a man's pants should not be too snug or too baggy at the legs. Stand in front of a mirror and make sure the pants drape correctly from your hips to your ankles. When walking around your pants should feel comfortable. If the pants bunch at the knees when you are walking, the pants are too tight. When the pants make a swishing sound as you walk, the pants are too loose.
The pants should end at the shoes with a slight break. Allow for about an inch to hang down on the shoes but no more than two.
Thank you so much for reading my article. Now that you are finished you should go to your closet and make sure that your current suits fit correctly. If they do not you can always have your tailor fix them for a small fee.
