In love with two dresses - help!

I recently went to pick up my dress from the bridal shop, and my worst nightmare happened - my dress came in wrong! After a lot of discussion with the store, we simply don’t have enough time to order a new one, so my options are limited to the store samples in my size.

Here is where the dilemma comes in. The store has a sample of the dress I originally ordered (first two pictures). However, after some encouragement by family, I tried on a few new dresses and fell in love with one (last two pictures).

Both dresses are stunning. The first one is classic, elegant, and sophisticated. The second one is whimsical, youthful, and intricate. My heart is absolutely torn between the two, which is why I’m coming to you, Reddit.

What do you think? Is there one that you love better than the other? Please help me choose!
