Difference between a size 12 and 12W?

There is a difference between a Misses size 12 and a Women's size 12W. Traditional plus or "women's" sizing is cut with a deeper arm hole, lower and larger bust-line, and larger waist compared to hip ratio than "Misses" sizes. This results in 12W being about one size larger than a Misses Size 12. This cut difference also means a better fit for differing body types. Those women with a traditional hour glass or pear body type will usually find a Misses size range fits better. Women who have a rounder, more Apple shaped figure and carry their weight mainly in the bust and abdomen, will find the traditional plus-size clothing or Women's Sizes will fit their figures better.
