Confidence-boosting clothing for women David's Bridal 9v9010

I ordered the dress online, the person who measured me sent in the wrong ones so the dress is to big. NEVER worn. I had it specially made for me. I want a corset backing and not zip, i want it to be ribbon back it came with a lot embroidery on it ( I do not like embroidery ) I PLANED ON WEARING MY BOOTS WITH IT BUT IT IS STILL TO LONG FOR ME. I am only 5ft 2. I wanted it to have completely removable sleeves so the sleeves can come completely off.
