I did the regular adjustments to the pattern before cutting out to the bodice front. To accommodate my small bust I narrowed the bust darts and moved the horizontal dart up almost an inch. I took out about 1/2" (on each side) between the apex of the bust and the center front. Although I cut out a 12 for this pattern, I have teeny tiny shoulders so I cut out just smaller than an 8 for my shoulders at the top of the shoulder and tapered it out to a 12 at the waist. Since the armholes were smaller, this affected the sleeves and so I gathered them at the armhole and around the edge with binding to finish them off. This was much easier than trying to re-configure the sleeve.
I used an invisible zipper on the side and finished off the collar with some cute vintage lace from my dearly-departed grandma's stash of lace. Thanks Grandma!
Below is a picture of the bodice front alterations that I made to this pattern. Deciding which alterations to make take a long time, but they are well-worth a good fitting garment.
