I've done this before with a fairly simple sweater pattern for my daughter, but I want to make this sweater:

and I'd like to change it to make it knit in the round up to the armholes. I'd like to keep it somewhat fitted though, do you think I'd need to leave off any of the stitches that are supposed to be seam allowance? If so, how many on each side?
