Remember that numbered sizes will vary greatly from store to store, so if you're unsure of your size, getting measured correctly will be the best way to insure fit.
~Important! Waist measurement must be taken by bending sideways and measuring where the body creases. Other store sizes will not be as accurate as having these measurements taken. Small is roughly a juniors' 7/8, misses' 4/6. Medium roughly a juniors' 11/13 or a misses' 10/12. Large roughly equals a juniors' 17 and a misses' 14/16. Extra Large roughly fits a juniors' 23, misses' 20/22, and plus size 18W. Remember that knits and stretchy fabrics will fit more leniently than non-stretchy or woven fabrics, and that blousey items will fit looser than fitted ones.~
