Denim is known for its flexible material; how it gives either warmth in winter or fits cooler in the summer. It is reputed as a 'maternity fashion staple' type of jean that can be both casual and fit for dressier occasions. Denim also allows for a wide range of styles. If you were a fan of low-rise jeans, they offer them in maternity sizes as well. Rugged maternity jeans for around-the-house occasions or work pants and eve lunch with the girls are easy to find in darker shades to suit your taste.

Unless you are aware of the terms used by manufacturers, buying a pair of maternity jeans can be confusing and overwhelming. They come in a wide variety of styles, shades and fits so it will be easier to find the best pair for your body if you understand what to look for.

The rule of thumb is to look for the size you wore before you became pregnant. Maternity denim jeans are made to either fit over the developing bump, to fit under it or to fit where your natural waist was before. An 'under the bump' pair of jeans is constructed with a jersey panel that is made up of a supportive band of wide but comfortable elastic that, as the name states, fits under the bump of your growing abdomen. This type of jean is best for expectant mothers who are in the first trimmest of their pregnancy. On the other hand, a fully elasticized waistband is one that fits above the bump of your abdomen. Some women prefer this type of jean while others do not.

If you hear the term, jersey basque, this means that the front panel of the jeans is made of a soft stretch jersey material that has the ability to expand, as your abdomen grows larger. This is a good choice for the whole duration of your pregnancy. The jersey basque has an adjustable elastic that is not evident to the outside and it helps to encourage the comfort and fit of the garment.

Any pregnant lady will appreciate denim maternity jeans with side panels as women will widen from side to side as well as out in front as they progress in their pregnancy. As your body grows larger, the elasticized jersey side panels are also able to expand. There are certain women that like drawstrings because of the comfort that they bring. As a woman moves along in her pregnancy, comfort is sometimes hard to achieve in the clothing she wears. Drawstrings are waistbands with elastic in the back and an adjustable draw cord in the front of the pants. This helps to keep them up.
