37-27-36 here.

Try different brands. I am currently all over the map!
I wear mostly 6/8's, but my really old (pre-vanity sized) Gap 10's feel awfully darn comfy.
I bought a size 2 skirt the other day at The Limited.
Dresses for me are an 8/10.
So truly, your measurements are excellent.

We're all just shopping in different places.
