When choosing a plus size pant suit, the primary thing you should be concerned with is fit. You want to find items which accentuate the positives of your body while minimizing the appearance of any trouble spots. It's generally a good idea to choose pants which are the right length and a jacket which is fitted in order to highlight the smallest part of your body, which usually sits just below the breastbone.
There are various shops which specialize in plus size clothing, although some department stores also have plus size sections available for plus sizes. The first thing to consider when choosing a plus size pant suit, is that you will need one which comes with pants designed in the right shape for your body. Wide-legged or straight leg fit may balance out large hips or breasts by adding depth to your lower legs.
You should also choose pants which are long enough, but which do not drag the floor. Choosing options with added details, like pinstripes, and a straight leg will also elongate the legs and give you a sleeker look. Skinny legged options are available, if your legs are your trouble spot, this may add extra emphasis on extra weight in the hips and thighs.
Choose a jacket which fits slightly tighter toward beneath the breast area to give yourself an hourglass shape. The arms should still meet your wrists even when raising your arms over your head, but they should not extend beyond the wrists when your arms are down by your side. The jacket should also not be too tight under the arms and you should be able to move freely.
Another important aspect to choosing a plus size pant suit is the shirt you pair with it. Bright colors, patterns, and ruffles may all draw attention away from trouble spots. Do not wear tops which are too low-cut, primarily if you have a larger bust. Instead, opt for blouses with necklines which sit just above cleavage. This, combined with colors which accent your skin tone, will draw attention toward your face.
If you have trouble finding a plus size pant suit which fits properly, buy one in a size larger than you need and have it tailored to fit the way you want. You can also have a suit custom made, although this option is generally much more expensive. It is also sometimes possible to buy both pants and matching jackets separately, so if you need a larger bottom than top or vice versa, this allowed you purchase the size you need for each piece.
