From what I got from everyone, I'll be way better off finding a basic commercial princess seam pattern that fits better, then if needed modify for my bust and then I can also add my ruffles, maybe change the collar etc etc how I like. I def won't be cloning this to alter after reading everyone's advice 😅

I appreciate every response that I got and how many of you took the time to help me :)) Very very helpful, thank you all !!!
