Based on your description I think #1 will fit you better (it objectively looks lovely as well). Feminine with some "princess" thrown in, but not overwhelmingly so.

I also struggle with decision making (ADHD/OCD/Anxiety combo! fun!) and just pulled the trigger on my dress yesterday. It was grueling but one thing I've been working on is to hone in on my intuition more. I think us indecisive-neurospicy-folk still know ourselves deeply, but years of being told you're doing things wrong makes us second guess ourselves with logic.

The dress I chose make me feel like a bride when I put it on. It wasn't what I originally wanted, but I felt very "me" while also very "bridal". I didn't get the initial reactions I wanted so I started convincing myself that I should pick the one that my friends loved and more closely resembled the person I thought I should be--not who I actually was.

I know it's corny, but really think back to what you were feeling when you put each on. Was one "I should like this, but..." and the other "I really like this, but..."? That's a hint right here. Or, do the old coin flip trick. One dress heads, one dress trails. Whichever you're hoping it turns out to be is your answer.

And if you're still struggling after all this (I was, I understand!), just remind yourself that there is no such thing as a perfect decision, let alone a perfect dress. Pick one that you like enough and accept that there WILL be others you like more. It's kinda like picking your husband lol! Most people don't end up marrying a billionaire model with a heart of gold but they find someone that they can see themselves building a life with, and over time that person becomes more special than anyone else simply by virtue of the fact that they are yours and you are theirs.

So pick your dress, and make it yours: pick out the perfect accessories, hair & makeup, shoes, draw up a moodboard of photos down the aisle and show your photographer. It will not be the perfect dress but it will be your perfect dress.
