Everyone knows the feeling of spending hours finding the perfect pair of men's or women's designer jeans only to find out they sag and pull in all the wrong spots. Deciphering the sizing isn't as difficult as you think. Finding the perfect fit for both women's and men's designer jeans requires a few moments of measuring and a few tips about the difference material has on size to decide what size of pants you'll need.

Find the Magic Number

The first and most important part of finding the right size of men's or women's designer jeans is finding out what your measurements are. First, use a measuring tape to measure your waist at the point where your pants generally sit and add an additional two inches. For most denim wearers, this is either on or just over your hipbone.

The inseam, from the crotch to the hem of the pantleg, is the next measurement you will need to know. Last, get your crotch length by measuring from where the four seams meet in the middle of the pants to the top of the waist band. As a general rule for women, if you subtract two from your waist size, you will come up with your pant size. For men, simply add two inches to your waist size and you're done.

Exceptions

The material and design of each pair of jeans can also have a big impact on the size of jeans you should purchase. For denim with stretch, you can often go one size smaller. For those that don't stretch or contain spandex, you are best to go up one size. Another great place to look when it comes to finding jeans that fit is the zipper. If it doesn't lay down flat, the jeans are too small.

Style Choice

The style of women's designer jeans you choose should also be taken into consideration. Average women with generous booties should look for jeans with little mid section decoration and stretchy legs. Tall and narrow women should choose form-fitting jeans with tapered cuffs and big pockets. Shorter girls can maximize their assets by selecting wider or casual fit jeans with light decoration running down the legs.

The opposite is true in men's designer jeans. Men with larger builds look best in darker jeans that have a higher waistband and casual width legs. For smaller men, consider denim with narrower legs and a shorter waistband. For tall and average males, opt for wider legs and busier designs to look your best.

Finding a pair of men's and women's designer jeans should be more about finding the styles and colors you like rather than worrying over the size. Once you know your measurements, you can find the size that works. Considering your body type will give your size choice an added boost and help you find that pair of designer denim jeans you won't want to take off!
