Hi to everyone who's put their name down and I have to say it's a big thrill to see that button on a few blogs too, it makes me feel all professional at this and stuff :)
I've been doing a bit of looking around at tunics and investigating the Full Bust Adjustment (FBA) idea. It seems like it's what I've been missing from my repertoire!
What I didn't know about patterns is that they are drafted to fit a B-cup (which simply reflects the size differential from your full bust point to your ribcage). So even if you size up to accommodate your larger bust, you will be making a larger size that's still drafted for a B-cup differential. WTF? That's just nuts. I do not know many women who would be making a size 50 for example, who would have a B-cup. Anyways, this totally explains why tops often don't fit when I've chosen the size for my bust. It's why the tunic I just made is slightly too large everywhere except across the bust (still). There are lots of tutorials online about how to do a FBA. Here and here look like good ones. The book everyone recommends though, and one that's now on my wishlist, is one called Fit for Real People by Patty Palmer. Looks like a must-have if you're planning on making a lot of your clothes. I think I might try making the Summer Shirt again but with the FBA and see how it goes.
I've also hunted down some alternative tunic patterns
The Shearwater Caftan looks essentially the same as the Heather Ross one I made
The Patricia Tunic, the Shana Bell Sleeve and the Tribeca Tunic are much more structured garments
The Schoolhouse Tunic is the most similar to the tunic I have that I'd like to replicate, although it looks a bit boxy - but it might just be that particular fabric. I think I'd convert the box pleats to soft gathers in the centre. The only issue I can see with this one is that it appears there is no shaping through the bust at all, but I found a tutorial on how to do a FBA when there's no bust dart so it shouldn't be an issue.
I haven't done a search through the commercial patterns yet, there may be good stuff - if you have a great tunic pattern, or have experience with FBA let us know!
