Nell, i had the same problem...would have loved burnt orange but my BMs are pale and said it didn't suit them. They were also doubtful that it'd go with my other colour - teal, although since I've showed people moodboards of the colours they've changed their minds! We comprimised on coral though, which goes with teal better anyway!
In case people missed it, here are some links to dresses I've found, pasted from the other thread :\):

I really wanted the below dress but one BM didn't like:

My girls loved this one but turned out to be a bit too orangey.. they are reduced to £50 in store though
