text: Women's sizes are extremely tricky because they vary alot by manufacturer/designer and cut.  Also, more expensive clothes tend to run larger than cheaper clothes (e.g., a size 8 dress from a more expensive designer might be equivalent to a size 10 dress from a less expensive designer). The other tricky thing is that there are misses sizes and womens sizes.  In many cases, 0-16 is misses and 18+ is womens, but there are some manufacturers who make 18 in both misses and womens and the proportions are slightly different (misses are a little smaller). Here are a couple of examples:\n\nsize 18 misses(from Land's End)\n43" bust\n36" waist\n46" hip\n\nsize 18 womens (from Lands End)\n44.5" bust\n36.5" bust\n47" hip\n\nsize 18 womens (from J Jill, a little more expensive than Land's End)\n44" bust\n36" waist\n46" hip\n\nsize 18 misses (from J Jill)\n43" bust\n35.5" waist\n45.5" hip\n\nsize 18 misses (from Chadwicks, less expensive than Land's End, multiple brands)\n41.5"-43" bust\n33"-34.5" waist\n43.5"-45" low hip\n\nsize 18 womens (Chadwicks)\n42"-43.5" bust\n34"-35.5" waist\n44"=45.5" low hip\n\nMost websites that sell women's clothing will have a size chart--typically it's part of the "customer service" page.  Hope this helps!
