You might try www.ccoriginals.com for patterns. They have about 40 doll clothes pattern sizes for fashion, girl and baby dolls and a doll body measurement chart to get the perfect fit. Hope this helps.
I used to find these patterns in the Singer, McCall's pattern books for sewing at fabric shops.
Try ebay, too.
You can also guess at a pattern from interfacing (which is cheap), cut and paste until it fits and then cut it out of the real fabric.
Here is a web address that has patterns and descriptions for dresses for 15 to 18 inch dolls.
When I've been desperate for a pattern in the past, I've just taken a current article of clothing and traced a new pattern from it. As long as the clothing isn't too complicated, you can usually make a new garment from this pattern by just adding on a seam allowance of 3/8 inch or so. When I was a little girl I had hours of fun going through my mom's fabric scraps making outfit after outfit for my doll this way. What a nice grandma you are!!
