Dress doesn’t fit my top

I purchased my dress over a year and a half ago. Plenty of time. I spent 2200$ on a very pretty and simple boho designer dress. I had them close the back with a zipper so i could be comfortable and wear a bra and the v neck line would allow me to nurse my 22 month old. I did 4 fittings every time they said you boobs need to be higher and me saying they just don’t go that high and then I’d buy new undergarments that were still inadequate.. the dress is beautiful except for the bust it just doesn’t fit. Even with to a of tape. I broke out in a rash from the tape and it’s so uncomfortable and everything i was trying to avoid by buying a simple boho dress. I spent an extra 700$ on 4 alterations on top of the 2200$ and another 400$ on bras and shape wear and tape and it still doesn’t fit right. I have two weeks left until we hit the road for the wedding. How bad would it be just to wear a simple linen jumpsuit and call it a day. I just want to feel like myself and be comfortable. I thought by spending obscene amounts of money i would have a really beautiful perfectly fitted dress. But i just don’t. I feel inadequate, foolish and ridiculous.

So disappointed
