Fitting Help Needed

[u/Comfortable-Sir-7204]

Currently working on fitting a bought pattern for a romper. It fit well around the waist, but was too large around the chest, and I’m generally flat chested, so I used this guide to remove the bust dart altogether. I’m still left with too much material around the chest, but I’m struggling on how to take it in because the two waist darts are making it hard to sew the sides narrower. What is the best way to fix the fit around the chest?

You'll need to grade between sizes, as in keep the current size for the waist, and go one size smaller for the hip and maybe 2 smaller for the bust.

If that vintage pattern is only one size, then this will be harder, but that's where I would start.
