The best thing about trouser jeans is that there are so many to choose from now! It used to be that there were a couple of styles, and they were scary and looked like mom-jeans (you know the kind - high waisted, pleated (yikes!), and hiked up under the armpits). First rule of trouser jeans - NO PLEATS!!! They only serve to add four or five inches to one's midsection...NOT a good look for any girl. This is especially apt when shopping for plus-size fashions.
Check out Old Navy online - they have several different styles of trouser jeans. Stick with the darker washes for a slimming effect. The Diva Low-Rise Wide-Leg Trouser jeans are a great choice. Also, I really like the look of the Mariner Low-Rise jeans. They have styles in straight leg, wide leg, bootcut, even colored jeans! So many great choices. For an updated trouser jean look for spring and summer, try the Flirt classic-rise wide leg chambray jeans. Lighter-weight fabric, sits just below the waist with a wider waistband.
Another great trouser jean is Svboda 'Kate' Stretch Denim Trouser Jeans. The ultra dark wash is very flatttering, as is the dropped yoke waist and back welt pockets. Stick with welt pockets or the button-loop welt pockets - the style is much dressier and also more flattering.
