Dress color regret

I purchased my Stella York dress last June and tried it on in with a moscato underlay but ordered ivory/ivory. The last bit of my appointment was rushed by the consultant and I chose the color quickly without thinking too much about it. The sales associate held up a small square of ivory fabric to show me what it would look like and didn’t tell me that the lace would almost completely disappear with the ivory underlay. I called a couple weeks after I ordered and tried to change it to moscato but was firmly told that the order had been placed and there’s nothing I can do. I haven’t been able to get my mind off all this and am picking my dress up in 1.5 weeks and scared I’m not going to like the dress in ivory/ivory. I never got to try it on in ivory since the sample was moscato. I’m just venting and wondering if anyone else has been in my position? I am going to be devastated if I see the ivory/ivory version and am not crazy about it.
