It wasn't "the one"

I tried it on again and my heart just dropped. I hated it. So i tried on a few more dresses, 2 of them very contenders, but i don't want to jump into one again without taking some time to think.
I'm so frustrated at this point i could cry. Still unsure of my deposit, but as of now the saleswoman said i could put it towards another dress at the store. I wondering if I could just get it back if i dont find anything there.
