Hi sunnyco,

I own an online sewing supplies & notions store at www.ciscosewingsuppliesandnotions.com and I have a bunch of older/vintage patterns I will be selling on that site. Please watch for them.
I don't think I have the specific pattern you are looking for but, if you have the pattern (even in a smaller size than you need) why don't you just alter it to fit you?
I have been learning more and more about pattern altering and now enjoy it very much. In fact I regularly buy patterns in smaller sizes and alter them to fit me. I find that certain, more difficult areas to fit (necklines, shoulders, etc.) fit me better in a smaller size but letting out the waistline and/or hip is really easy!
I watched a couple of dvds to give me the education and courage to do this. If you want to use your pattern, check out the Fit for Real People dvd at http://www.palmerpletsch.com/dvd-videos.htm.
Marta gives very basic, easy-to-follow, instructions for altering patterns. You can apply them to any pattern. There's an accompanying book too but I found the video great for seeing what she's doing as she's explaining it. I've used her methods many times and had great success.
If you just don't want to do this, another option is to get someone (like me?) to do it for you. I also do custom sewing and I'm sure we could arrange something. You can contact me by going to my webstore that I mentioned above. All my contact info is on that site. Good Luck with your project!

If you do a search for 'vintage sewing patterns', you will have lots of sites come up. Some charge a lot for their patterns, but many are reasonable. You can also find vintage patterns on eBay and Etsy.
The last few years I have been nostalgic for the patterns I used(and was able to wear,LOL)back in the 70's. It was a favorite "style time" for me. The 'retro' patterns they make now just don't have that certain look, and they seem kind of tacky to me. I can no longer wear the type of clothes I used to back then, but when DH and I moved across the country several years ago, I left garbage bags full of old patterns. Now I wish I had them. I've even re-purchased a few of my favorites(for many times the original price)that I used to have, just so I could tell my GDs, "I made that and I wore it!". Silly, yes?

Have you tried checking the company website yet? Most of them have discontinued pattern services - for a price.....
