Wedding shopping!!!

So, we went shopping ALL day Friday and was finally found my mothers gown and found I think my shoes!!! My mothers gown is a copper color which in my opinion looks awesome!! We are now just unsure what to put my mother-in-law in I am thinking a gun powder silver or something in that family.... any thoughts....? My girls are in a color called sangria (purple/wine) and the guys are all in black tuxes so any suggestions shes not a picky person at all.  Oh and my flutes/rings I now have visited once this week while waiting for them to come in!!
