I'm an experienced seamstress who recently started knitting. After countless hours of fitting woven garments, it's a bit of an understatement to say that fitting a knitted sweater is giving me a lot of anxiety. The reason for this is that I have very forward set shoulders. This causes the shoulder seam to run towards the back. In extreme cases, the shoulder back not quite wide enough and there is too much fabric across the front.
Here is a threadbare RTW T-shirt. You can see the diagonal creases along the back caused by my shoulder pulling it forward. I have identical T-shirts that I wear less often that don't fit this well.
In flat patterns, the simple adjustment is to redraw the shoulder seam by removing a piece from the front and giving it to the back. The front shoulder ends up with a steeper slope, while the front has a flatter slope. The sleeve cap is also shifted to the front. This usually makes it impossible for vertical repeats to match at the shoulder seams.
Here's a woven shirt I made with a forward shoulder adjustment. The shoulder seam runs along the top of my shoulders. Sadly, those vertical stripes don't match.
When it comes to RTW, the shoulder seam often fits worse on knitted garments than it does with woven garments. Here is a Croft & Barrow sweater that fits all kinds of wrong in the shoulder area. It doesn't help that the shoulder seam sits too far back even at the base of the neck.
I've looked at quite a lot of information regarding fitting knitted sweaters, but I can't find anyone discussing this type of adjustment. Would I go about this the same way I would with a woven fabric? Are there any sort of issues I should be aware of?
