For those of you who are curious to see the 2nd prototype, here's the fit test with the internal sleeves in place:
It fit really nicely, but because the position of the arms was different...
...it made the fit at the shoulders change near the neck. This is why it's so important to do a fit test with any alterations you make: a change in position of the arms makes the shape of the shoulders different. Edits like this can ripple though the entire pattern. So if you still want a skin tight fit, you may have to make adjustments along the way.
