what color shoes???

You can just let them pick whatever shoe colors they want to wear unless you are going to buy it for them

I think a metallic shoe would look best. The leather looks to casual.

I'd say go with a wedge vs the chunky heals. They look super casual. Stay with a nude color.

OP, are you paying for the shoes or are your BMs?

I told my BM's silver shoes.. any style any height and I didn't pay for them....

I would go with a nude color. Most people will have a nude shoe, though it might not be an appropriate heel for grass. I just asked my BM's to wear silver shoes of their choosing but at my venue there isn't any grass to contend with. Wedges like PP's are a good idea. Or if they want a stiletto, maybe you can get them Solemates or another heel protector so they don't sink.

If it's a long dress who cares?

I think nude or silver colours will be nice!

If you are buying I would go with a a metallic or nude wedge.

If they are buying I would go with nude whatever they want.
