Gosh so many replies!
In answer to some comments.
My wondeful daughter is happy for me to wear whatever I feel comfortable in. The bridesmaids are in green. I suit dark colours, anything pale makes me look washed out. I really don't like bright colours. I have not mentioned my shoe size at all! I am now very confused as to what colour shoes and bag to choose, but they definitely won't be nude or gold!
Edited to add - I hoped that asking outside of my circle would give me a more balanced view of the suitability of the dress. I'm more confused than I was before!
