What kind of jeans are good if you are chubby as I want to buy some?

 There is something called as high waist jeans. Wearing this style of a jean will flatter your chubby stomach like anything else. The wide belt area works as an efficient tool to cover your big belly and gives you a balanced physic.
For better effect wear it with a short tunic. For a women with extra weight in her middle, a flared jeans too will do the same magic. They give your body a proper and deceiving balance despite an imperfect tummy. Wearing with a shirt tucked-in feels too cool.  Gone are the days when women with extra flesh on their hips and legs would be forced to stay away from wearing any type of jeans. Wearing of some flattering jeans, by chubby women, has become much acceptable these days. Jeans for women with heavy legs are available in abundance.

Lane Bryant has jeans called  Right Fit, they measure your waist and hips and they have three different color codes, Yellow, Red, and Blue. I am a Red...a curvy shape. Yellow is Straight, so if your current jeans fit the waist but are baggy, or they fit the hips and thighs, but have to be unbuttoned.Red, is if your current jeans ride down the back of your waist and blue is if they gape in the back or you have to cinch the waist cause your waist and hips aren't balance out.
Right now they are having a sale they are $39.99. There are plenty of styles for women, so please dont rush to the men's department they are not meant for our curves.
