Not Excited About My Dress

So I’ve seen so many dress regret posts, but I didn’t think I’d have that problem. I bought my dress the first time I went shopping, I tried on like 5 dresses total. By time my dress came in, it was a little too big, so when i tried it on, I didn’t really love it. As time went on, it got even bigger on me, so I figured the not loving it part was coming from it not fitting well. So I got my dress altered and picked it up today... I don’t love it. I just don’t feel it at all. I’ve spent $1500 and I’m getting married in 3 weeks, so a different dress is 100% out of the question. I just don’t know how to make myself feel better. I only have a pic in it from the first time I tried it on, I’ll post it. It’s a gorgeous dress, I’m just not excited about it for whatever reason.
