Wedding dress

Hello everyone,
I would like to ask for your suggestion about my wedding dress.
I made a mistake that I bought a wedding dress on an online website. I like the style, but material looks cheap and the size is a little bit tight for me. I decided to shop around my local stores with a hope to find a better dress. I found 2 dresses at David Bridal:1. About $1300 (without tax and alteration)- I like this one- almost everything (but need alteration for sure- about $500+), but the price concerns me a lot. I can afford it, but my gut tells me that I should not spend too much on dress (especially I already paid $600 on the first one)2. About $500 (without tax and alteration)- I like this one, but there is some small parts in the dress that I don’t like. I do not know what to do. I know it an once in a life event, maybe should not spend too much on dress. But on the other hand, I concern that I might regret that I did not wear the one I love.Please advice me.Thank you in advance
