Now my sewing mojo is back (thanks to the slip) I got motivated to alter the Butterick 4976 Chetta B. wrap dress that I've made a few times. It always bugged me that it was kind of a loose fit in the upper body despite making the smallest size (8 in pattern sizing, which I never usually make - this pattern has lots of ease as it's designed for either wovens or stable knits.)
So I decided to follow Sandra Betzina's steps to "petite" the upper body contained in her book Fast Fit - basically shortened the front, back and upper sleeve by 1" by drawing a line perpendicular to the grain, just above the notches on each piece, and folding that line up 1/2", then filling in/blending the line to make it smooth.
Here it is (excuse the cell phone pics):
Front View - decided to mix up the usual hands-on-hips routine

Back

Side (tied the obi-style belt the way it was intended, and in front, so the knot adds a bit of bulk, I think - probably need to switch it to the side the way I usually wear it)

It worked pretty well, as the fit is much better (darts are now in the right place and upper body fits more closely) but I still need a cami, so I didn't meet my ultimate goal. I have one more thing to try next time - making more of a crossover in the front (i.e., sewing down the cross over part of the neck closer to the side seams, which is what I did with one other pattern to make it fit nicely in the chest. If that doesn't work, I'll resign myself to the fact that camis may always be needed for me with wrap dresses unless I'm willing to show cleavage, which I'm decidedly NOT. I'm not even comfortable showing it when I'm out with Jim, and he's not either, as he'll shoot worried looks in my direction and tell me frequently that I'm "losing my top" and to adjust it so I can't relax. And obviously I'm not going to do it in a business setting, despite the multitude of people who seem to be just a-ok with it. I mean, it's distracting to ME as a hetero female to see half of someone's bra in a meeting, so I'm guessing it's extremely distracting to men! Sorry, rant mode off.
And I know I'm pretty small-chested to have this cleavage problem, but because I'm so short from shoulder to bust, despite only measuring 33.5" in the full bust, cleavage is pretty much a given if the neckline is open any lower than about 7" from my shoulder (measured diagonally, like a raglan seam would be - as I was curious and decided to measure.) The shoulder is also a little bit off my natural shoulder (maybe 1/2") so I'd like to fix that too but am not sure how to do that, unless I would just make the shoulder part of the pattern pieces narrower by shaving off some of the end that meets the sleeve cap. I also want to tweak the neckband piece as it was slightly too long and I had a tiny bit of a problem sewing it on.
Overall, though, I think it's an improvement and the next one should be even better! I think I want to do this with a few of my favorite patterns - alter them to make them even better to get true TNTs!
