I have been on a quest for Levis for a long time.  I'm at the age when they just don't seem to fit properly, either too small in the waist but fit everywhere else, or fit at the waist and are much to big in the hips!  Along came Silight curve Levis!  I normally wear a 12 or 14 but going by measurements I went with the 16.  They fit but after I wear them awhile they are a little baggy, so I ordered a 14 and they are perfect.  I'm keeping the 16's tho for around the house, they are that comfortable.  Don't let the size numbers bother you, it's just a number!  Whether you are slight curve, demi curve, etc. I'm confident you will find a pair to fit.  If they don't, you know how easy it is to return at Amazon.
Just give them a try, if you're like me, you will be delighted!
