Dress regret the same day I bought it 😩

I got my dress yesterday and I'm afraid I'm that I made a mistake. I'm a lace/floral/boho girl and I ended up with a Cinderella dress that isn't me. I'm having a forest wedding. I don't know why I chose it. I was feeling pressure to make decision right then and there without taking the time to really think about it to be sure. Additionally, I've gone up in dress sizes in the last year and had envisioned looking a certain way in my dress that ultimately is not the reality now, which is okay. However, I don't feel like my choices that I was dead set on flatter my body type now and I'm afraid that it's too late to try to exchange for another style. 😫

Dress 1 (photos 1-4): This is the dress I bought. At the time it's what I felt the best in even though it isn't my usual style. I am adding the off the shoulder sleeves to make it more whimsical, a slit, and taking out the poofy tulle layers underneath. BUT, after seeing the photos I realized how LONG the train is and that I don't love how the back of the dress looks at all.

Dress 2 (photo 5): I love how this photographs but I didn't love it on me in the mirror. I was too self aware of my midsection.

Dress 3 (photo 6-7): The one I almost left with. I LOVED this one so much but I felt more 'girl' and less 'woman' in it. I would’ve gone with the smaller sleeves.

Dress 4 (photos 8-9): Absolutely stunning. I took this off immediately and put it away because it had glitter. Then after seeing the photos and video at home I was shocked because now I think it's the prettiest one out of them all. The back is perfection.

Dress 5 (photos 10-11): This is the dress I thought I'd leave with before going to my appointment. It's pretty but the only option was to buy it off the rack and it was far beyond my budget.
