I found a whole bunch here: http://m-sewing.com/patterns-catalog/women/pants/dark-silk-pants.html. Not all of them are there, but many many are.
Actually, once you've made the basics at least once successfully: shirt, pants, dress, corset, hat, shoes, etc. All you really need after that is just the cutting layout. Many of them are constructed generally the same way
Having realized that, it opens up a gigantic deluge of possibilities. For instance: If you go here... http://www.uri.edu/library/special_collections/COPA/index.php. And just do a search of their sample database, they quite generously give you the cutting layout for everything, most of the time. It's jaw dropping really. Their database spans a vast dictionary of fashion from the late 1800s, through each decade, including my favorite, the 20s, right up to the very recent 2010. Bless their hearts. It is a subscription service of course, so if you want more information for a particular garment, you can choose from several subscription options all very reasonable, and I may do that if needed.... (Actually, I haven't quite figured out what it is you get with the subscription)
Let me demonstrate how using just a cutting layout, I can make a little pair of pants for a doll without further ado
Step 1: Materials
1/8 yard of material suitable for dolls clothes: anything with a very fine weave that drapes easily at small scale and wrinkles up nicely when you crinkle it, not too heavy. Actually you only need half that much, but the smallest cut you can get at the sewing store is 1/8 yard which is 4 1/2" wide
seam ripper, aka the undo button
scissors sharpener (recommended)
one or two sets of hook and eye closures
a doll to be your mini-mannequin
Step 2: Cut Each Piece Carefully
Print out the attached pattern on a sheet of 8 1/2" x 11" paper. I measured my doll and she is about 6.5 inches from waist to ankle. I'm using a 1/4" seam allowance, so 7 inches long should be about right.
Cut out each pattern piece from your chosen fabric. Flip the pattern pieces over and cut them again to get the mirror image of them.
Pinning fabric at this scale is counterproductive I find, so I just lay the piece down and trace around it with chalk as illustrated.
Use very sharp scissors and cut as accurately as you can. Where there is a dart indicated, just cut a little slit in.
Step 3: Make the Little Darts First
Step 4: Sew Inseams
Do the same for the other side pair of front and back pieces
Step 5: Sew Crotch Seam
sew along the crotch seam from the notch under the zipper, all the way along to the top of the waist as shown.
for best results, line up the two inseams and start sewing where they meet, then turn the piece around and sew the other direction from the inseam to the end
Step 6: Sew Outer Seam
(If you are going to do a bottom hem, which I probably should have and forgot to do, hem the ankles here first as this is your last chance to do it by machine)
Now fold the pants so that the right sides are together and the outer seams line up as in the second photo
Sew along the outer seams.
Step 7: Sew the Waistband and Fly Seam
Sew it on along the length of the waist edge
Fold waistband over wrong sides together and topstitch it down.
Fold fly seam over and stitch it down.
They don't make zippers this small, velcro is too bulky I think and so are snaps, so I used a hook and eye to close it. You might need two if it isn't closing up nicely.
Step 8: Finis
You could also scale these up or down for other sized dolls or even yourself!
