Here are my measurements...

5 ft 8 inch
145 pounds
waist 29 1/2 inch
hips 39 1/2 inches

I normally wear size (U.S) 8 in women's pants and a size 7 in panties.  I decided based on reviews to buy size 8 and they fit perfectly and look great.  They are soft cotton with full coverage and better yet, a hardly noticeable pantie line because it falls so low under the curve of my butt.  The colors i received were coral pink, a blue, and a pretty print that was a blend of the two.  Would buy again.
