Hi everyone, so I bought my dress last week

Firstly, what do you think?! It's by Maggie Sottero & the only colour that still felt bridal without washing me out, but it's not how I imagined my dress to be at all! Unfortunately the pic doesn't really show it, but it's got some beautiful embroidery all over it

Secondly, what colours do you think would go best with this dress for bridesmaid dresses, bouquets etc? I was thinking purple, but I'm not sure what shade would be best.
Thirdly, I'm the kinda gal who changes her hair colour a lot, do you think the blonde looks good with this dress or too princessy? I can't decide if I should keep the blonde or go back to a medium brown...
Fourthly, what kind of hair accessories would go nicely with this? Again I am worried of looking to princess like, so was wondering if I'd be better off with flowers or something.
Thanks!
