Briefly, the bodice top is huge and the sleeves are not cut on the stretchy grain of the knit fabric:
I can't take the bodice top in easily as this would distort the armhole shape. It also would not solve the problem of the tight sleeves. I also don't want to make this a baggy summer t-shirt by shortening the sleeves - this is a cheap fabric that was put on the muslin pile and it is too warm a fabric for summer.
I have thought about how to solve the problem. The first part was narrowing the bodice, which was quite a simple matter - I just folded out an inch vertically out of both the front and back pattern sections. I chopped off a portion of the sleeve length and then made up a little muslin. As I have already mentioned, I have previously resized the neck.
Well, this looks like a much better shape. I like this in it's own right as a short sleeve t-shirt - now I need to find something nice to make it in :) !
I also need to attend to the pocket of fabric that flops into my middle back. It is not a sway back problem, but comes from higher up - I have a narrow and erect back. I think I will have to alter this as a sway back problem though, as I can't easily do my narrow, erect back alteration on this cut.
The sleeves are still a problem, but I am still working on that...
When I have solved that problem, I will tell you :)
Wishing you a wonderful day
