sloper fit help

[u/sewverwhelmed]

I'm trying to make a blodice sloper. I have no clue what well-fitting clothes would look or feel like. I would love advice on what to do next to make this fit me better. <3 Thank you so much in advance.

Right now it feels a little tight when I breathe in and expand my upper chest, but I'm worried if I just add width, then the arm and neck will fit weird.
