I went to Old Navy this weekend, because my size 18 and 20 jeans are getting to big for me.  I decide I would go into Old Navy and give their jeans a try.  I tired on a pair if 18 low rise and it wasn't a good look.  So I looked at a chart they had in the fitting room and realized that  I would need to try the sweetheart jeans they are classic rise.  I tried on the 18 and they were a little to big so I tried the 16 and they fit.  I have never been able to fit into a pair of Old Navy jeans, I was so happy that a tear came to my eyes   I couldn't believe that was able to fit into a regulat pair of jeans.  So now I know that I can buy Old Navy jeans when my jeans gets to big.
