Activity for Mary

So we officially have a flower girl! Now a few questions to go along with it (: Are they supposed to be white/ivory to match my dress? Or can they be a different color? Our wedding colors are white, charcoal, and reds....I thought a red dress would...

I am having a Kentucky Derby tea party for my reception (big hats and all) but I'm having a hard time coming up with decor and centerpieces besides the obvious horse figurines. Anyone have any suggestions? Thanks so much!

I'm not really into veils but I know my father wants me to wear one, I was thinking about purchasing off ebay or etsy. Anyone purchase online, if so, any recommendations or red flags of where not to buy? Thanks!
