Unsure about wedding dress

I bought my wedding dress on Black Friday sales last year thinking that I would only go look at dresses and probably not find anything I liked. I walked into the boutique and tried on about ten dresses, and kept coming back to the plainest one which I liked the most. My mom was there and she really wanted me to go for something frilly or blingy, but I really liked the plain dress. I normally take my time making big decisions, but since it was Black Friday and the sales assistant told me it was the last one and that the price would go up exponentially if I waited, I decided to buy the dress. The more I look at the photo, the more I feel like I got caught up and cheated by the lies of specials. I don't feel like the dress flatters my figure and I fell like it makes me look like I don't have hips at all. I feel plain and boring in the dress, I also need to find seamless underwear for the dress as it shown EVERY little lump and bump.

I think the worst part is that no one reacted to the dress the same way I did. My mom hated it because it was too plain. My fiance disliked it, because it doesn't show off my curves and friends' reactions were sort-of like "it looks okay". So now I'm having severe doubts about the dress, as I want to walk down the isle and take my fiance's (and everyone attending) breath away.

I think another reason that the dress leaves a sour taste in my mouth is that the sales assistant lied to me. The dress is still the exact same price I paid for it and there are still plenty in stock. I'm wondering whether I'll like the dress more after alterations. I feel stupid for not taking my fiance with me to look at dresses. He is the person who's opinion matters the most to me. Maybe I wouldn't have made such a rash decision if he was there to guide me.

Please ignore my hair and face in the attached photos, my mom is the worst photographer on this planet.
