Here's my mess, after I cut out all the pattern pieces and ironed them flat.
Tissue fitting the bolero. Uh. I have no earthly idea how this will work - tissue doesn't drape like fabric. I figure another inch at the back seam and front seam will be a good start. Seems to be folding for upper chest decrease already. Hm. (Tissue fitting for me mostly functions as a starting point to making a muslin/toile).
I increased the seam allowance to 1" on every piece, which is the "couture standard". I traced off each piece rather than cutting and pasting - this pattern is a nice one, and it is out of print. I've mentioned the difference in how I treat patterns based on how nice/rare they are? Yeah. This one is meant to stay unslashed and untaped - I can't replace it, at least easily/cheaply, so it's worth the extra work.
As of now, I have the dress pieces all marked and cut out. Before I do anything else to them, I will thread-trace the alleged seamlines (so I know what I've changed). I left the hem allowance at 2".
Didn't get to the bolero ... I'm getting tired and the cutting lines on that are a little crazy. Don't do fiddly things when you're tired!!!
Oh, I don't do this muslin stuff to the facings and whatnot. I'll adjust those based off of the outer changes, after I'm done.
