table21, first check your emails, your order confirmation lists all the measurements you gave to Luxire.
Second, wash and measure your shirt, has Luxire followed the measurements you gave them correctly? Well, in case so, it's not their fault the shirt does not fit you.
If not, you can contact Theresa and discuss what you options are.
As for your shirt, obviously you need a greater bottom width, other from that it seems you have too little fabric in the back of the chest...
