Weddingbee boards

My colors are deep purple (grape) and silver. Bridesmaids (4 of them) are wearing the purple dresses. I have 1 Jr. bridesmaid i put in silver - it is a light silver chifon with a bit darker satin sash. I couldn't match the purple vests for the men so I am putting all the men (even the jr. groomsmen in silver) which I think will look good. Tie all the colors in!

Here is my dilema. We picked out the guys vests which are just a satin plain vest, no patterns or anything on the vest which we really like. More formal feeling to us.  However the vest mor of a grayish silver. So it is darker than the Jr. bridesmaid dress (her dress is a true silver). SO...I did find at Mens warehouse the EXACT silver shade to match the ONE only silver dress in my bridal party. However it has a slight pattern on it.

Question. Do you think I should change the vests and go lighter to match the jr. girls' dress - again only 1 girl wearing a silver dress? Or is the the darker siler/gray ok we already picked? My wedding is memorial weekend so I also starting thinking changing the vests to the lighter color may be better? Does it matter? I know too, at least i think, in pictures it will photograph lighter so the darker vests may be ok.

Opinions??

@auggiefrog:  Thanks for the input. You are probably right. And you think being a spring/Memorial weekend wedding the darker silver vest is ok? Probably doesn't matter. People do black in the summer right?!!!!
