One fun thing to do is take this dress, make a pattern from it, and then make some tailoring adjustments for your next dress. With each one, you will learn new techniques. It's sort of fun to learn how your body fits clothes. This book is very pattern-oriented, but it is amazing for figuring out "fit issues". Excuse all the dorky looking clothes and models. https://www.amazon.com/Fit-Real-People-Clothes-Pattern/dp/0935278656
Go to the site below, click on "Look Inside" and type "petite" in the search box. There will be a photo and discussion of two 5" women named Sharon and Kathy on page 22. One is short and the other is petite.

I'm glad you appreciated it! I have one more for you, the cover of this book, Fit for Real People, is horrible but I swear the info inside is totally worth it. It teaches tissue fitting patterns so that you can solve fitting problems BEFORE you've spent a bunch of time making a garment to find that it fits all wrong. I freaking love that book.
Ninja edit because I screwed up my link.
Bing bing bing! That would be great if your boobs were located under your armpits. :D
Yes, you need to add the fullness where the mountains are located. There are different methods for an FBA and I've even created a few more. Too bad I never made a video, but lots of ppl follow my blog for this very reason.
Anyway, as a starting point, I recommend:
By the way, I use different techniques for knits, wovens, princess seams, etc.
Good luck!
There are two different options for you. For minor adjustments like adjusting the bust, moving the waist or hipline in or out a bit, etc. you can just do a regular pattern adjustment. Fit for Real People (http://www.amazon.com/Fit-Real-People-Clothes-Pattern/dp/0935278656) is a really great how-to on adjusting tissue patterns for fit issues.
For anything more than minor adjustments (say more than 1-2 sizes different) you're going to need to grade the pattern. If you use the minor adjustment method above you'll lose the structure and proportion of the pattern. Here are two online tutorials on grading, I'm sure there are more. http://www.craftsy.com/article/pattern-grading http://www.threadsmagazine.com/item/4368/making-sense-of-pattern-grading/page/all
Since these are vintage patterns you'll probably want to trace them out (you can get good tracing paper at most craft, office supply, and art stores) and then use the tracings to make any adjustments. I've also had good results using wrapping paper since its cheap and available in large sizes. As an added bonus it makes my patterns look really festive.
Do you know if this person mostly quilts or sews clothing? If they are in to clothing, I wouldn't get them Fat Quarters or other mainly quilting supplies, and vice versa.
For a quilter, perhaps a few spools of Aurfil Thread, Fat Quarters, Wonder Clips, or Soak Flatter (starch alternative)
For an apparel seamstress, maybe a roll of Swedish Tracing Paper, a book on fitting patterns, or a few yards of fabric from Mood.
