It seems like the average waist size is between 25 and 27 inches. But mine is 31 inches yet I fit into S/M tops and size 6 bottoms when on sizing charts it says I should be wearing L/XL and 10-12? All this sizing stuff confuses me LOL. Could I just be big boned? Or is it maybe vanity sizing? And on a sidenote, how do you reduce inches in your waist besides the obvious "lose more fat"? Any way to get the "hourglass" waist where it goes in at the sides?
