I am normally a size 8 but read reviews about sizing up.  I ordered an 11 and they were very tight in the thigh and around my big butt.  I liked the length, I am 5'1" and they came just below the knee.  They are light weight but just heavy enough to hid panty lines and whatnot.  Im going to try a size 13.  The size of the jeans go up as my self esteem goes down.
