Dress change?

So I never in a million years thought I'd be one of the brides who changes her mind once she bought a dress. We're on a tight budget and I got a great deal on a Maggie Sottero. Lovely dress for around $100. In the pictures it looked like tons of lace, corset back and I loved it. In person, the lace is also accented by silver rhinestones and sequins. Still a lovely dress. But my accent color is gold. Some of my girls might even be wearing a matte gold for their dresses, or a burgundy. I feel like ivory and gold would work so much better.

Am I over thinking this? We're using all muted fall colors and gold as out theme. Has amy one done this with a bright white dress with silver accents? Does anyone agree that an ivory dress with gold accents ( like my tiara) would be more fitting?

Curious for opinions. I broke the news to my soon to be and he said as long as I sold the other dress, he was okay with me buying a new one in ivory. I've found one I like, custom made for around $150...
