Wedding Dress nightmare

We were due to marry in 2020 and like lots of people had to postpone. Various dates later that has to get moved we actually marry on the 21 May (a few weeks time).


BUT I hate my dress. I have had a bespoke dress made from a very well known designer and when I went in to see it for the first time last month it looked terrible and didn’t fit at all. They’ve made some changes but it still looks terrible. It’s like (and I’m actually a bit lighter so it’s not weight) there isn’t enough material at the top so you either have boob central on show at the front (which is not the design of the dress) or they sort my boobs out at the front and then my back is squashed in and looks terrible. I’m a size 14 and did not think a £4000 plus bespoke dress would be a terrible experience.
So upset. Does anyone have any advice where I can can get a new dress with literally just a few weeks to go off the shelf. Everywhere I look has just 1 sample. All advice welcome!
