Dress Alterations

So I just picked up my dress from the alterations lady and my wedding is in 6 weeks. I don’t like how it fits at and after I got home and tried it on for my mom I had a total breakdown. It’s an all plain satin dress so there is no anything to hide how it fits. It’s really snug mostly in the bust as I am a 34 I bra size so it’s nearly impossible to find anything that fits right regardless. My alterations lady was kinda rude and when pointing out all the areas it didn’t fit right as the neckline not laying flat. A weird underboob crease, she said well just drink some lemon water you’ll be fine and would even listen to my concerns so I just left with the dress. I tried it on with every bra I own and nothing make it’s look right, but it’s not that I have to lose weight or wear spans as nothing will make my bra size go down. I’m just at such a loss if I should take it somewhere else to see what they can do or just accept it looks strange and deal with it. Thanks I’m advance!
